I have a Windows 2000 domain. All servers are running W2K Advanced server w/ SP4.
There are two domain controllers. Both are global catalogs.
Active directory is replicating OK and there are Gig links between all servers.
There are also two Exchange 2000 Enterprise servers w/ SP3.
The EX1 server on an almost daily basis will stop responding once or twice. We usually notice this when we are in Outlook (2000) and a message pops up stating that Outlook is waiting for a response from the Exchange server. When I go to the server all the Exchange service will be running but the ESM will be unresponsive like the stores are dismounted. Trying to stop and re-start services does no good, it times out stopping the info store service. The only way to get EX1 functioning again is to reboot. Looking in the Application event logs I see Events 2103 (MSExchangeDSAccess) and 2110 (MSExchangeDSAccess). This made me look at connectivity, DNS and WINS. A netdiag /v on EX1 showed that the server discovered both DC's (and GC'c) OK and returned no errors. Dcdiag looks good. DNS and WINS seem to be functioning correctly and do not have incorrect entries. Security/permissions on EX1 (in ADSI Edit) look OK.
I noticed that when I go into the properties of EX1 in ESM and click on the Directory Assess tab I receive an error saying:
"Information about Directory Services could not be entirely obtained. Check to see that Microsoft Exchange Management service is running on the Exchange 2000 server." (The service is installed and running.)
Once I click OK the Directory Access tab is viewable but all normal configurable options are grayed out and only DC1 is listed instead of both DC's, bith GC's and the Configuration DC (like on EX2). I am not able to click or change/select anything.
When I try to do the same for EX2 everything is normal an working fine.
Does anyone have ideas what is causing this? What am I overlooking?
