Can't find DC !!!

By Whatme? ·
I have a DC at site 3 which went offline for some reason. I rebooted it but it can't find or bind to a DC. NTFRS went offline since it ca't rteplicate with the other DCs. I get a 1000 usr error saying no DC to log onto. Active Directory can't be reached on this dc. I checked microsoft site but it said take server or workstation off domain and join again but this is a dc and if it can't replicate it sure won't depromote itself.
I can open my network places and see and open other workstations.

Any ideas?

This is starting to get exiting....
DNS is working properly... end. As stated after question 2. I have narrowed it down ( or I think I have) to an IPSEC issue. For some reason DC3 went offline. When it came back on it did not authenticate to the main DC1. I "think" I have to somehow delete any referebce to use IPSEC...but it is greyed out in TCP/IP. I can use Ipsec configuartion and analysis but it is denied... since the main DC initiated the policy. All DCs worked except this one. I need to over ride the DC policy and enforce a local policy....I think... man is this confusing sometimes...

Hi there. As I understand you can access your DC by remote control, don't you? As you describe the problems you have, tells me that the your AD on that DC are corrupted somehow. The only thing you have to do is to try to restore the AD. The problem is that you can't do that by remote control. Sorry for the news.

As it turned from anser 6... I can do a remote. It worked quite well. I actually went ahead and did a restore of system state. After restarting, it failed...still to contact the other DCs and active directory is still unavailable locally.

Answer 5: Don't think I want to try that yet. I would have to travel over there to do that.... no one elase around. There has to be a better option.. and that is what I am looking for.... that slim option that will work.

Maybe this link can start you off on the AD recovering issue.

Hope it helps in some way (1500 miles are a lot of miles)

Tried this, and thought maybe I was on to something here but not. Restore worked ok but failed to connect to my main domain to update AD. I then tried DCPROMO and tried a demotion but it failed again since I can't authenticate to domain. Stupid thing is I can open network neighborhood and open any workstation and open shared folders without being asked for user creds.

Take a look at the services, make sure the Remote procedure call (RPC) service are running. You might also want check the DNS Server service and the rest of the services.

Sorry... very first thing I checked All necessary services..DNS,DHCP RPC working ok.
in event viewer in applications I get a 1000 user error. Windows cannot determine user or computer name
in File Replication service... error 13562... could not bind to a DC
In services error 5719... no NT or DC availabale for domain xxx
currently no logon servrs to serve request.

These all arise out of not being able to contact other DCs and replicate and clocal cached copy is kaput I suspect.

I know this is going to sound stupid but, why don't you try to have someone install something like PC_Anywhere for you in the remote machine, and you do the same in the one you can manage. That way it would be like managing the remote computer with your own hands (you can take full control of the machine). It's not expensive and saves you lots of cash in plane tickets.
