AD problem

[Just Another Admin]

Hi,

I am having some trouble here. This is the trouble I am having.

Around 1-2 weeks ago I had a DC crash (lost 2 Drives in a RAID5). So I
decided to simply restore my new DC with the same name. I didnt even use
previous backups to restore because I didnt have anything on it. I simply
reinstalled the server and did a dcpromo and the whole AD got replicated.
Ever since I have notice a couple of weird things for example on the
Security Event viewer I dont see any new PC or users connecting to it but my
other DC (which holds the GC also) is getting all teh requests. The other
problem is that Exchange is not communicating AD with it. The reason is that
I created a new user recently and it told me that the user didnt have the
rights to logon for the first time, so what I did was shutdown the new DC
and it worked. I am wondering why is that. I tested the AD Replication and
that works perfect. it replicates perfectly. Any help would be appreciated.

Thank you

G.

P.S Sorry my English is not that good.

I would guess at some GUID related problems because you are using the same
server name. Try demoting that server back to a member server and then do a
metadata cleanup of AD and DNS to remove all references to it. Then you can
re-promote it and all should hopefully be well again.
This is the metadata cleanup process:
