Thanks Meinholf,
I checked DNS and cleaned up a few things. (thanks)
The only pointer to outside IP addresses is in the forwarders Tab section of
the DNS server's properties. All other addresses are internal.
All the NS records point to live servers that are up and running and are
hosting an operational DNS.
When I restart the problematic server it runs fine for an hour or two during
which time I am able to start AD Users and Computers, etc.
During the normal hour or to I notice that after a while I am unable to view
some windows event logs using event viewer. I get different error messages.
Some saying "access is denied" and others saying that there was insufficient
information to determine the cause of the error. This happens on logs that I
would have successfully viewed a few minutes earlier. After the RPC problem
starts then I cannot successfully view and Windows Event logs.
(in a worse case scenario, can I just install widows server2003 over w2k8?)
Thanks for your help.

Hello Joe,.
Check that DNS is only pointing to internal DNS servers. Did you run dcdiag
/v and netdiag /v to check for errors?

On a brand new Dell Server I have installed Windows Server 2008
standard
edition.
The existing domain is controlled by a two server win 2003 AD setup
and as
part of the installation on the nw server I upgraded the schema of AD
2003 to
be compatible with AD 2008.
After booting the server I have access to AD Users and Computers (and
windows logs via event viewer) for a short while but eventually I get
the error (when trying to load AD Users and Computers):-
"Naming information cannot be located because:
The RPC server is unavailble.
Contact your administrator to verify that your domain is properly
configured
and is currently online"
When this happens I also have problems viewing the windows logs using
Event
Viewer. I get the following message when trying to view the Windows
Application or System logs:-
"One or more logs in the query have errors
Log: System (or Application, etc)
Error: Insufficient information exists to identify the cause of
faiure"
I then demoted the server from being a DC and de-installed AD DS.
Once I do that I have no problem with the event viewer.
I have two other DC's on the network (AD 2003 upgraded to AD 2008
schema).
With the addition of Win Serv 2008 I wanted to have three DC's and I
configured all three as Global Catalogs (Don't know if this is
required as its only a small network with no inter-site
communications). I set all three as GC's so that any one of them
could process logons and authentication in case of a single server
failure.
The only thing I can think of is completely re-installing the OS but
if I do that I cannot think that I would do anything differently.
There are two network cards. One disabled and one active. I have
unticked TCP/IPv6 on both cards as they were causing error messages as
they weren't fully configured.
The server has 4GB RAM and loads of free disk space.
Can anybody help?
