Servers with duplicate SIDs

Medium Priority

Last Modified: 2012-05-11
Hi,

I have three Win 2008 R2 production servers, one with SQL, one with SQLRS and one with IIS installed that have ended up with the same SIDs as a trusting domain. I have confirmed this with psgetsid.

I need to, if possible, generate new SIDs for these serves without killing the installed apps.

Is this even possible? Could I take them off the domain, run Ghostwalker , or can I run SysPrep (making sure the generalize box is ticked) to generate new SIDs, and rejoin to the domain without killing the installs?

It's really going to be a major problem if I have to rebuild the servers from scratch. They are VMs so I can take clones/snapshots etc to try things out.

Any advice welcome, thanks

Run newsid to change the SID:

Rejoin the servers after reboot.

Thanks for the replies. I will clone all machines and try sysprep on the clones.

Will sysprep not kill SQL, IIS, SharePoint etc?

Thanks for the replies. MS has never support newSID, and it doesn't work on W2008, although it works great on XP and W2003

I haven't had chance to try sysprep yet as other commitments have occurred but I will try it out.
