Well, you need to start by troubleshooting:

a)      What services didn't start (e.g. you need NetLogon, Kerberos Key 
Distribution Centre, DNS etc)

b)      Why they didn't start

The single dc that we restored in the dr lab was indeed a gc. However, nothing 
came up. Dns wouldn't even start. Dns is on all of our dc's.

Not enough information.

Where is your DNS? Do you have an entry for a GC that points to your remaining 
DC?

You need a GC to populate Universal Group membership (or you need Universal 
Group membership caching enabled). No GC = no logon (except using cached 
credentials)

Guys, quick question... We're doing a mock disaster recovery here. Can we spin 
up a child dc without also spinning up a DFR dc and get it to work well enough 
to start AD, authenticate users, etc? We've tried it already and it hasn't 
worked so far. I suspect it's due to the lack of an accessible _msdcs zone.

Thanks!
