RIS GUID screwup

[Charles Blair]

We had a machine that was having problems booting to the RIS server, so we
took its hard drive and installed it to another computer. From the second
computer we booted to RIS and downloaded an image. On the first reboot,
after the file copy segment of the RIS process, we installed the hard drive
back into the first machine and completed the setup. Unfortunately, now
when we boot to RIS on the second computer, it shows the first computers
name for the image. So the first computer is now owner of the GUID that RIS
is trying to assign to the second computer. Is there any way to get out of
this situation? Is there a way to reset the GUID of the first computer?

TIA

I figured it out. Just delete the computer account in AD and rejoin the
domain.

fyi ... ensure you delete the computer account or else, when you rejoin, you
will just attach to the same account with the duplicate GUID. If the
account is deleted, it will create a new account with a new GUID.

I also found some references to changing the GUID for the existing account
by finding the UUID in the computers BIOS and entering this correct value on
the computer accounts Remote Install tab.

I hope this helps anyone else looking for a fix.
