Corrupt Domain Controller
I've just spent the day getting a corrupted server back up and running.
However, it's now clear that there is some faults with the domain controller (plenty of errors in the log and any changes made to AD are not showing on the other domain controllers).
It's clear I need to demote this server, but how can I be sure that this is the last domain controller in the domain?
I've been looking at this thread:
and it seems that I may need to seize the roles to another controller. How can I tell what roles each domain controller has?
There are two other working DCs on my network, this one which has failed is the oldest and I'm not sure what the previous NM did regarding the roles.
I was planning on phasing out this old DC at the end of this year (during the last week of term while everyone's watching DVDs!), but the hardware failure has brought things forward somewhat.
