Paul,

I do daily incrementals on my servers. I have not restored a DC yet, but I have 
successfully restored non-DC server's System Objects files successfully. Only 
real issue would be to do an authoritative AD restore, where you are 
exclusively overwriting AD database. Other than that the regular AD restore 
should be easy, since other DCs in your domain will update the restored DC's db 
via replication after restore.

Check out section 6.2.4 of Redbook sg246141.pdf. It talks specifically about 
what you want to do.

I will be conducting an AD restore before the end of this year as a test. I 
will share my experience then.

Thanks!...I just discovered that Redbook yesterday and I am working my
way through it...Follow-up questions for you:

Are you using TSM to backup the Sytem Object--Daily-Weekly-Monthly on
your DC's? Have you ever had to restore a DC with TSM?

Thanks!
