I am working for a client and must re-install their existing SBS2008 server installation onto new hardware. I have tried a bare metal restore onto the new server but it fails to boot after the restore. I suspect driver issues.
My other option is to do a scratch install of SBS2008 on the new server and then manually configure it for PCs, users etc.
I have heard that instead of having to take the client PCs off the old server domain and to re-add them onto the new server, its possible to change the security ids somehow.
How did you perform the restore? Boot from SBS2008 media and restore from recovery?
If so the drivers which are preventing the server to boot should have been replaced by the DVD and boot time.
Any other way i am not sure what you could do.... if you clean install all workstations need to rejoin the domain since the new domain has no trustrelations with them anymore.
