Sysprep /generalize

So once again, my techs have used a clone, this is the second one in as many months, this practice has been fixed though :)

With that said....

Domain A, has a trust with Domain B

Domain A cant authenticate to domain B

In domain A I am going from the DC to a file server in domain B

Low and behold both DC-A and FileServer-B have the same SID.
In the event viewer I get NULL SID.

I need to use sysprep /generalize on the file server. This is the only thing on this server just files and shares. Now its fairly big, 4TB. We have adequate backups.

As far as I know, I can run sysprep /generalize on it with no issues.

Anyone know if its going to reset all of my shares and permissions?

I'm not 100% certain, but just thinking about the process...
Shares - yes (it will reset/remove these).
NTFS permissions - no.

Do I need to disjoin it from the domain?
I typically disjoin it before running sysprep, but running it will also remove any knowledge from the machine that it was joined to a domain (the account in AD would remain however).
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

This has been completed:

Disjoin server, run sysprep, rename, rejoin all ok.

it did NOT remove my system shares.
it did NOT reset any security on shares or drives

All is well and the computer has a new sid.
I'm surprised it didn't remove the shares.
Glad it worked out for you.
