Fix Windows 7 Boot

Fixing the Master Boot Record (MBR)

Step one: Boot from either your Windows 7 Installation DVD or Windows 7 System Recovery Disc.   Remember, you may need to change the boot order inside your BIOS to have the your DVD drive boot first.

Step two: After the installation or recovery disc loads, if prompted, select your language settings and then continue.   If you are using the installation DVD, when prompted by the following screen select Repair your computer.

Step three: The computer will take a moment now to scan itself for any Windows installations, after which you will likely be given a choice to select which installation you wish to repair.   Select the appropriate Windows installation from the list and then continue. If by chance a problem is detected in one of your Windows installations at this initial stage, the system may also ask you if it can try to repair the problem automatically. It is up to you if you wish to let the system try to repair itself, but otherwise just select No.  

Step four: Once you have reached the System Recovery Options screen, as shown below, you will be faced with a list of choices that can aid you in repairing a damaged Windows 7 operating system.   If you wish to try the Startup Repair option first, it is often successful in automatically fixing many different start up issues, but in this article we will be using the Command Prompt option to resolve our problems manually. So, click Command Prompt to continue.  

Step five: Now sitting at the command prompt, enter the following command and then press enter:

                bootrec.exe /FixMbr

If successful, you should be greeted with the message The operation completed successfully.   That's it!   Your Master Boot Record has been repaired.

While the above command does fix the MBR, and sometimes that is enough, there still might be an error with the system partition's boot sector and Boot Configuration Data (BCD). This might occur if you have tried to install another operating system alongside Windows 7, such as Windows XP.   To write a new boot sector, try the following command:

              bootrec.exe /FixBoot

If you are still faced with your Windows 7 installation not being detected during start up, or if you wish to include more than one operating system choice to your system's boot list, you can try the following command to rebuild your BCD:
              
              bootrec.exe /RebuildBcd

The above command will scan all your disks for other operating systems compatible with Windows 7 and allow you to add them to your system's boot list. If this fails, you may need to backup the old BCD folder* and create a new one in its place with the following commands:

              bcdedit /export C:\BCD_Backup

              c:

              cd boot

              attrib bcd -s -h -r

              ren c:\boot\bcd bcd.old

              bootrec /RebuildBcd

*Some users also find simply deleting the boot folder and retrying the above steps effective at resolving boot issues, but it is not recommended.


How to change active partitions

Upon purposely changing the active partition on my system drive, I was faced with a BOOTMGR is missing error during my system's start up that prevent Windows from starting. It is a common mistake to make when playing with partitions on a system drive and it can be a headache to solve if not prepared. To change your active partition back using the Windows 7 recovery disc or Installation DVD, follow the steps below.

Step one: Follow steps one to four in the above guide. This should take you to the Command Prompt in the Windows Recovery Environment.

Step two: Type DiskPart and then press Enter.

Step three: Type List Disk now and then press Enter. This command will list all disks attached to your computer and assign them a disk number.

Step four: Type Select Disk x, where x is the number for the disk containing the partition you wish to make active. Press Enter.

Step five: Type List Partition and then press Enter. You will now be shown a list of the partitions on the selected disk. Determine which partition you wish to make active.

Step six: Type Select Partition x, where x is the number of the partition you wish to make active.

Step seven: Now, just type Active and then press Enter. That should be it - the selected partition is now active.

How to create a Windows 7 System Recovery Disc

Windows 7 makes it easy to create a System Recovery Disc if you already have Windows 7 installed and running.  

Step one: Click Start > All Programs > Maintenance > Create a System Repair Disc

Step two: Insert a blank CD or DVD into your disc drive.

Step three: Click Create disc and let the program do its thing.

That's it! It only needs to write about 140- to 160-megabytes to the disc, depending on whether your OS is 64-bit or 32-bit, and that should only take a minute. If you do not have a CD/DVD-R drive to create a recovery disc with, you can alternatively download the ISO image of the Windows 7 System Recovery Disc and use it to make a bootable USB flash drive.

How to create a Windows 7 System Recovery USB flash drive

Step one: If you do not have a DVD drive, download the appropriate Windows 7 Recovery Disc image. Alternatively, if you have a DVD drive, you can use an existing Windows 7 Installation DVD or a Windows 7 Recovery Disc when at step seven.  

Using a Windows 7 Installation DVD at step seven will also allow you to install Windows 7 via USB, not just recover a damaged system; very useful if you have a netbook!

Step two: Open a command prompt with administrative rights. To do this, click Start > All Programs > Accessories and then right click Command Prompt, followed by clicking Run as administrator.

Step three: After accepting any UAC verification questions, you should now be at the command prompt. Make sure your USB flash drive is plugged in and then type DiskPart, followed by pressing Enter.

Step four: Type List Disk and then press Enter. Determine which disk number corresponds to your USB flash drive. In the following scenario, Disk 1 corresponds to our USB drive since we know our USB drive has a capacity of 2-gigabytes.

Step five: Enter the following commands in order, changing the disk number to the disk number listed for your USB drive.   Warning - the following commands will erase everything on your USB drive or the disk you select.

              Select Disk 1

              Clean

              Create Partition Primary

              Select Partition 1

              Active

              Format FS=NTFS

Step six: After DiskPart successfully formats the USB drive, which might take a few minutes, you will want to enter the following commands:

              Assign
              Exit

Step seven: You will now need to copy the contents of the ISO image you downloaded, or the contents of a DVD you wish use, to the USB flash drive.   There should be two folders and a file in the ISO image that need to be copied. To extract the files contained within an ISO image, you will need to use a program such as 7-zip.

Step eight: Now that the files are copied, we will want to make the USB drive bootable. To accomplish this however we will need to download a small file called bootsect.exe; it can be found in the boot directory of the Windows 7 Installation DVD.  Once downloaded, place the bootsect.exe file in the root directory of your USB flash drive.

Step nine: Back at the command prompt, we will want to change the current directory to that of the USB drive and run the bootsect command. In our case this is drive E, so we will be using the following respective commands:

                 e:
                 bootsect /nt60 e:

The bootsect command will update the target volume with a compatible bootcode. If all goes well, you should now have a bootable USB recovery drive; just remember to add the USB drive to the boot list in your system's BIOS for it to work upon start up.

when runing setup DO NOT check "Automatically install Windows Server roles and features required for Exchange Server"

DO NOT REBOOT!
DO NOT START Exchange Management Console yet!

Install Exch2010 SP3

reboot

You may find that on Server2012 you can launch the Exchange Management Console, but are unable to expand any of the objects in the left hand pane.
Exchange 2010 Exchange Management Console was built with CLR (Common Language Runtime) version 2.0. Windows 2012/8 by default runs its MMC snap ins with CLR version 4.0.
to fix it, start cmd and type:

set __COMPAT_LAYER=RUNASINVOKER
set COMPLUS_Version=v2.0.50727
"C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc"


Now you can do the usual stuff.

BTW: Don't be an idiot (like me), don\t install Eset RA Server before installing Exchange, that will put the Exchage RA web console on ports :80 and :443 and IIS will never start. 
netstat -a -b -n -p tcp is your friend in this case, run it and you will see who occupies your ports.

Reset the username and password on a Symbol WS-2000

The cause of this error in my specific case was that the SSL certificate was no longer bound to the Exchange Back End website on that Exchange 2013 server.

To fix this, in IIS Manager right-click the Exchange Back End website and click Bindings.

Highlight https and click Edit.

If you see “Not selected” like I did, click on Select.

Choose the certificate you want to bind to the site.

Apply the changes and retry the Exchange management shell. If it connects successfully to the server then you have most likely resolved this issue.

Deploy local printers to Windows XP

- Go to a computer without any printer installed, login as administrator and  install all the printers you need to deploy.
- download & run UTFG://printmig.exe go to Actions and click on Backup - save the cab file with the name printers.cab
- download  UTFG://ListComps.exe and run listcomps.exe /D:MY_DOMAIN >> comps.txt
  (replace MY_DOMAIN with the domain you're in) edit the file comps.txt in order to remove unwanted computers, servers...
- in a command prompt type the following line: for /F %r in (comps.txt) do printmig.exe -i -r printers.cab \\%r 
- now watch printmig spawning an instance for every computer and pushing the drivers to all of them
- enjoy a beer 

if before you want to remove ALL the old network printers you can use my (somehow pretty drastic) method of deleting.

Install HPSUM on an rpm base distro

mount /dev/cdrom /mnt

cp /mnt/compaq/psp/linux /tmp/

cd /tmp/linux

./hpsum

- check for the prerequisite, usually you need expect, kernel-headers, rpm-build, gcc, libnl, redhat-rpm-config, openipmi and net-snmp  either form the redhat installation dvd (rpm -Uvh package), or you can use "yum install package" if you have yum repositories configured.

- you need to manually install hp-snmp-agents package from the hp dvd, it is not installed by hpsum (I presume it's a glitch). hp-snmp-agents needs hp-health (you find them both in the /tmp/linux directory that you just copied from the dvd)

- re-run ./hpsum untill you have no conflicts/unresolved dependecies!

- after installation and reboot run /sbin/hpsnmpconfig - you have to provide only the readonly (public) and the read/write (private) comunity for snmp.

- if everything seems ok, edit /opt/hp/hp-snmp-agents/cma.conf lin 22: trapemail . at the end of the line replace root with your email address - REMEMBER: you need a functional sendmail in order to be able to send emails!

HP Important Note:   The server needs to have 'sudo' installed in order to start or stop the snmp daemon and to send test traps.   'sudo' grants controlled root access to groups or users.   If installed after hp-snmp-agents please run a '/sbin/hpsnmpconfig'. In case of VMware ESX 3.x series, please run '/etc/init.d/hpasm reconfigure' after installation of hpasm.   These buttons will NOT work if 'sudo' is configured to only run when the user is logged into a 'real' tty.   To be able to perform the operations of start, stop, restart of the snmpd daemon, the user must comment out the line 'Defaults requiretty' in the /etc/sudoers file.   See man sudoers for details about the 'requiretty' flag.   If present, this flag will need to be removed from the '/etc/sudoers' configuration file.   The 'send trap' button also requires a tool snmptrap to be present on the system.   This tool is often bundled with the snmp stack (Suse) or in a package called 'net-snmp-util' (Red Hat).

DNS Adbock on router

In case you have, like me, a secodary dns on your DD-WRT router, you need a dns adblock on it too. By modifying the excellent tutorial from http://www.howtogeek.com/51477/how-to-remove-advertisements-with-pixelserv-on-dd-wrt/ I came to this script:

Using Intel AMT’s embedded VNC server

Intel Chipsets with vPro/Intel AMT, paired with a Core i5/i7 or Xeon with integrated graphics, have a feature called Remote KVM.

To activate it, press Ctrl-P at the BIOS - this brings you to the MEBx menu, set a password (minimum 8 characters, mixed case, numbers and special characters are enforced - try to avoid #@$% - use star or exclamation), configure the network settings (DHCP, or static - it can even match the OS’s IP address!), enable Remote KVM and disable User Opt-In.

in order to set it up, download the Intel AMT SDK from http://software.intel.com/en-us/articles/download-the-latest-intel-amt-software-development-kit-sdk/ extract the ZIP and open ./Windows/Intel_AMT/Bin/KVM/KVMControlApplication.exe. (I had to install .net 2.0 in my wine in order to be able to run it.)
There, you can enable KVM by clicking "Edit Machine Settings" as seen in the following screenshot:

KVM Status can either be set to
-“redirection ports” (meaning it will only be accessible to clients that specifically support Intel AMT, such as RealVNC Viewer Plus or Intel’s KVM Console, the former of which costs $100, the later constantly overlays a RealVNC logo on the screen), or to
-“default port” (meaning it will be accessible on TCP port 5900 with any VNC client), or to
-“all ports” (which is the combination of both).
If you enable VNC access, you will also need to set an RFB Password. Warning, the password gets truncated at 8 characters but     at the same time has the security requirements identical to the general AMT password (Capital, small letter, number and special-character - WARNING: underscore is not special char, @$%&| are NOT allowed, choose star or exclamation to play safe).
If you disabled User Opt-In in the MEBx menu, you can disable it here as well.

Now you can use almost any VNC client you like (KRDC, Real, Ultra, and Tight VNC works fine, while TigerVNC seems to be unable to auth, and Apple Remote Desktop appears to cause the VNC server to freeze - it's Apple crap, what do you expect?).

Two things worth mentioning:
1: the initial BIOS splash screen is not visible during a KVM connection (not even on a directly-attached screen), so to get to the BIOS, you needed to blindly hit the F10.
2: it is not possible to enter the MEBx menu during a KVM connection (probably for security reasons), if you hit the corresponding CTRL+P key, it immediately exits and continues normal boot; if you establish a KVM connection while already in MEBx, you get disconnected immediately.

 If you’re building a home server, you should definitely consider getting system with Intel vPro/AMT 6.0 or later, you get ILO-like remote management capabilities for free.

Oh yeah, http://your_machine:16992 gives you access to logs, power control, network setup, users, exactly the same way ILO does!

And of course the OS has no idea something is running below him, there is no CPU load, on the host netstat shows no other connections except my ssh:
 tcp        0      0 192.168.aaa.xxx:22          192.168.aaa.yyy:49506       ESTABLISHED 2314/sshd

while from my workstation we can see a second connection to the VNC port 5900:
tcp        0      0 192.168.aaa.yyy:49506       192.168.aaa.xxx:22          ESTABLISHED 13362/ssh   
tcp        0      0 192.168.aaa.yyy:43311       192.168.aaa.xxx:5900        ESTABLISHED 29457/krdc

 Note the black blinking monitors in the upper-right corner - that screams "AMT":

Error 512 - rear chassis fan not detected on a Small Form Factor

as per hp site:
"Although the HP Compaq 8200 Elite Small Form Factor PC has no rear chassis fan installed, this error message may arise when the front panel cable assembly was damaged after a system repair attempt.
In a HP Compaq 8200 Elite Small Form Factor PC, Pin10 on the front panel cable connector is used to tell the system BIOS, that the chassis is a Desktop model, not Microtower model. This is necessary because the system board is also used in HP Compaq 8200 Elite Microtower PC, which has a rear chassis fan installed. Pin10 is not connected there.
If the cable on Pin10 of the connector in a HP Compaq 8200 Elite Small Form Factor PC was damaged accidently and therefore has no connection to the system board, the BIOS assumes that it is a Microtower model and therefore checks for a rear chassis fan."

There is a problem with the front panel connector:

Let's remove it and look, the pin 10 is not connected while pin 5 (usually unused) it is:

We just need to remove the plug from pin 5 and move it to pin10:

Finally the ground is moved from pin 5 to pin 10:

HP ILO Linux - reset password

(hpsum must be already installed)

Reset Administrator password to “newpass”:

vi reset-password.xml

<ribcl VERSION="2.0">

<login USER_LOGIN="Administrator" PASSWORD="something_without_importance">

  <user_INFO MODE="write">

   <mod_USER USER_LOGIN="Administrator">

    <password value="newpass"/>

   </mod_USER>

  </user_INFO>

</login>

</ribcl>

hponcfg -f reset-password.xml -l log.txt ; cat log.txt

Add user "admin" with password "nosecurity":

vi  adduser.xml

<ribcl version="2.0">

<login user_login="Administrator" password="blah_blah_it_doesnt_matter">

<user_info mode="write">

<add_USER

USER_NAME="admin"

USER_LOGIN="admin"

PASSWORD="nosecurity">

<reset_SERVER_PRIV   value = "Y" />

<admin_PRIV   value = "Y" />

</add_USER>

</user_info>

</login>

</ribcl>

hponcfg -f adduser.xml -l log.txt ; cat log.txt

Recursive owner and rights changing on subfolders

We assume the username==folder_name

the specific version for vista+ profiles:

@echo off
Echo (c) 2012 s@toma.gXXX
Set rprofiles=D:\path\to\profiles
For /f "delims=.V2" %%* in ('dir %rprofiles% /B') Do (
echo target is %rprofiles%\%%*.V2 User is %USERDOMAIN%\%%*
takeown /f "%rprofiles%\%%*.V2" /r
icacls "%rprofiles%\%%*.V2" /setowner %USERDOMAIN%\%%* /T /C
icacls "%rprofiles%\%%*.V2" /grant:r %USERDOMAIN%\%%*:F Administrateurs:F System:F /T
rem dir /B /W "%rprofiles%\%%*.V2"
rem ping -n 1 -w 1000 1.1.1.1 >nul
)

or the simple version:

cd d:\path\to\folders\
For /f "Tokens=*" %* in ('dir /B') Do  @cacls %* /E /C /T /G "%*":F

RD Shadow in 2012 R2

PS:>

Import-Module RemoteDesktopServices

Get-RDUserSession | select UserName,SessionId,UnifiedSessionId

mstsc /shadow:%UnifiedSessionId” /control /noConsentPrompt

the SessionId and UnifiedSessionId might have to be used, depending on how the wind blows and at what angle the Sun is on the sky :)

Resize an LVM partition on a HP Proliant server

1. Install HP Proliant support pack 

2. If you've installed the PSP before and it is already running on your server, you can skip this step, otherwise start HP Array Configuration Utility Online for Linux. 
cd /opt/compaq/cpqacuxe/bld
./cpqacuxe -R
note: after finishing online configuration utility, you might want to stop it by running
./cpqacuxe -stop

3. Expand array and logical drive
Go to https://localhost:2381 and click on array configuration utility link.
Click on expand array - it will take some time to finish (like 8hrs). After the expansion is finished, a new button called 'expand logical drive' will appear, clicking on it will finish expanding the array.

4. Make Linux kernel recognize the new size of your hardware raid5
Reboot Linux server, run  'partprobe' or 'sfdisk -R /dev/cciss/c0d0' followed by  'fdisk -l /dev/cciss/c0d0' multiple times, 'till it shows the new size.
You might have to reboot multiple times if the new size does not appear at fdisk -l.

5. Enlarge partition with fdisk - DANGEROUS, please have a full backup first!
fdisk /dev/cciss/c0d0  (you might consider using fdisk -u /dev/cciss/c0d0 - it will display the size in sectors instead of cyclinders)
"p" - take note where the /dev/cciss/c0d0p2 (your extended partition) starts!
press "d" then "2" to remove the c0d0p2 partition - yes you wil DELETE the partition, don't reboot, don't move, dont even breathe on top of that server!!!
press "n" for new, then "p" primary partition to use the full space
Make sure the old and new partition starts at the same cylinder or sector position, otherwise, all your data will be destroyed!!!
press "t" to change partition type to LVM
"w" to write
"q" to quit
now you will need to reboot again!

6. Resize physical volume size, logical volume size and perform file system online increase:

After reboot, check again the new size:
[root@log ~]# fdisk -l /dev/cciss/c0d0
Disk /dev/cciss/c0d0: 1799.7 GB, 1799797127168 bytes
255 heads, 63 sectors/track, 218812 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

           Device Boot      Start         End      Blocks   Id  System
/dev/cciss/c0d0p1   *           1          13      104391   83  Linux
/dev/cciss/c0d0p2              14      218813  1757509959+  8e  Linux LVM

Let's see ho many free phisical blocks we have:
[root@log ~]#vgdisplay -v | grep "Free PE"
    Finding all volume groups
    Finding volume group "VolGroup00"
  Total PE / Free PE    54337 / 17879

Now let's resize the phisical volume:
[root@log ~]# pvresize /dev/cciss/c0d0p2
  Physical volume "/dev/cciss/c0d0p2" changed
  1 physical volume(s) resized / 0 physical volume(s) not resized
 
  note: we used vgdisplay -v to check the number of free PE, let's say it's 17879.

Now let's extend the lvm: 
[root@log ~]# lvextend -l +17879 /dev/VolGroup00/LogVol02
  Extending logical volume LogVol02 to 1.60 TB
  Logical volume LogVol02 successfully resized

And finally we will resize the filesystem:
[root@log ~]# resize2fs /dev/VolGroup00/LogVol02
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/VolGroup00/LogVol02 is mounted on /data; on-line resizing required
Performing an on-line resize of /dev/VolGroup00/LogVol02 to 430276608 (4k) blocks.
The filesystem on /dev/VolGroup00/LogVol02 is now 430276608 blocks long.

Ofc, steps 4 to 6 can be replaced with running offline gparted from a CD...
