domain member server problems

[Guest ACE-Joe]

I have an NT4 server running Exchange 5.5 in a Server 2003 interim mode AD

domain. Just today, the server started experiencing issues that make me

think its related to the computer account or secure channel between the

server and the domain. When I try to start services sch as Exchange

services, which run under a domain account, I get error: 2140 An internal

Windows NT error occurred.

 

If I reboot, I get the same issue. I checked DNS, and I'm only using

internal DNS servers. I have my hosts and lmhosts setup just fine with all

the proper entries which worked fine for years and has not changed. I am

thinking about joining the server to a workgroup and then re-joining it to

the domain to see if that will fix it. I've also tried netdom command line

switches to reset the servers secure channel. I get access is denied and RPC

Server is unavailable when exectuting these commands.

 

From the server in question, I am able to browse network computers and

shares, and can even set the time against a domain controller. So there are

some things that work fine that I would think would be broken if this were a

problem with the secure channel, or computer account. I can also logon as a

domain account to the server without a problem. My netlogon service starts

without a problem, its just my exchange services, and network fax services

that are failing. All local services will start.

 

I am getting event ID 5722 on the NT4 BDC to which this server was

authenticating. I can see "Access denied" is the error detail in the event.

I tried resetting the secure channel from a 2003 domain controller, but got

the above errors about RPC and access denied.

 

So should I go ahead and try disjoing and re-joining the server to the

domain? Any other ideas of what I can try?

 

Thanks
