Change Windows 7 System ID

I've come into a situation where I have two Windows 7 laptops that were installed using a single image. Now, both of those laptops have the same system ID and it's causing me a few problems.  Does anyone know how I might change the system ID of one of those laptops?  Thanks.

I'd make a full backup first, then run SysPrep on one of them. (This should reset the SID and force you to re-enter the key)

Unfortunately, this user is remote and won't have access to the installation DVD.  I don't think you can run SysPrep w/o that?

ALWAYS test before trying as the solution, but sysprep in Win7 is located in c:\windows\system32\sysprep - the DVD should not be required.

I ran the sysprep and it said a fatal error occurred while trying to sysprep the machine.

That didn't help the problem.  Since this is a remote user, I've decided to wait and tackle this problem when he comes to the office in three weeks.  Too much of a down time risk if things go wrong.  I'll update you again in a few weeks.  Thanks.

I use ghostwalker, it's part of the Symantec Ghost Solution Suite, If you have that or can get it let me know and I'll post the command you need to run with it.

Actually, here it is had one of my disks here. BTW ghostwalker has to be ran from DOS or Freedos.


ghstwalk.exe /CN="LCSS-<RANDOM_NUMERIC>" /BV=1:1 /AV=ALL /IGNORE_ENCRYPTFILES /SURE

The user will be arriving next week, so hopefully I should be able to make some progress shortly.

I've got the user in house and am trying to resolve this issue.  I don't have the Symantec Ghost Solution Suite as mentioned.  Any other ideas?

C:\Windows\System32\sysprep\sysprep.exe /generalize /oobe /shutdown
 
That will reset your SID, if they are on a domain make sure to delete this computer from AD first after logging into this computer. When you restart the computer it will startup like you were setting it up for the first time but your things will still be on it.

I made a little headway......I didn't see that process running that leew mentioned.  Poking around online, I noticed someone with a similar problem.  By analyzing the sysprep logs they figured out their issue.  When I did that, I noticed that the first error message I received was

Failure occurred while executing drmv2clt.dll

Some more quick Googling led me to a forum where the user solved this issue by disabling/stopping the Windows Media Player Network Sharing Service.  When I stopped that service, sysprep ran immediately.

I'm currently running sysprep and will update soon.  Thanks.

I ran the sysprep and that didn't change the System ID either.  I got frustrated and just for matted the computer.  Thanks for everyone's help.
