Title: Virtual Domain Controllers

hehe - single DC - must have overread that - I would have called that to be a problem in itself ;-) 

But then again it's only for 10 users and likely ok.  As such, I even doubt that SID reissue is much of a problem as this environment is likely rather static rgd. new objects in AD ;-)

Well since it is a single domain and a single DC I would say he really doesn't have a worry about USN rollbacks but he does have a possible concern with SID reissue.

not really a useful approach to backup a DC. Might be ok for FS and other roles, but DCs are not really cool with snapshotting and being "rolled back in time" due the distributed nature of the data they store. You could easily cause USN rollback during recovery of a DC stored in this fashion (at least SP1 protects the rest of your DCs now by turning off in- and out-bount replication and disabling the netlogon-service if it finds a DC that's has a USN rollback status).

 

But for AD Backup/Restore you'd be much better off to work with normal SystemState backup/restore. Which is another reason why it's nice to have it on a separate box (virtual or hardware).

I run a single DC in a small environment... only about 10 users, and since it's just a single server office, and single DC domain... I just run everything on the domain controller.  Domain, DNS, File, Print, and Accounting Software on the same server... no VM ware... although I considered it.  Since it's a single domain server I just take ghost snapshots of the domain and then backup the files.

 

Seems to work pretty good, as it's been running solid for about a year now.

 

Thanks,

Could you just do the file/print on the DC?  In a small environment you could probably get away with it.

Hi All,

I have a question about running DCs on GSX server.  I understand that MS does not support this configuration, but I've heard that many people are running DCs in this fashion.  Can anyone give some advice in this arena?  The idea here is to do VM for a file/print, and another one for a DC in our remote sites.  Currently, we've got different hardware for each box, but we're trying to consolidate a bit out there.

Thank you.
