Topic: SID

[Bob]

Is there a SID in SME as there is in windows?
The reason I ask is that when you have workstations joined to a domain, after re-installing SME the workstations loose their user profiles and some software needs to be re-registered etc.
I would like to know if it can be done without having to reconfigure the workstations.
Obviously the domain and IP range and sever range etc will remain the same.

Thanks.
