I keep on getting an application Event ID: 2061 error every 5 minutes. The error states:
Process MAD.EXE An LDAP search call failed - Server=myserver Error code=80040957. Base DN=, Filter=(legacyExchangeDN=), Scope=2. I get no other application event errors.
This error seems to have to do with a communication problem between my GC and my Exchange 2003 server. Reading on this forum and other forums I read that I should be able to Telnet from my GC to my Exch2K3 server on port 389. However I get the error "Could not open connection to the host, on port 389". I also used the portqry program to check to see if my Exch2K3 server is listening on port 389 and it's not. I get "NOT LISTENING". Email seems to be working, I do get a lot of complains from the end users that they are getting the pop up box in the system tray "Outlook is trying to retrieve data from the Microsoft Exchange Server myserver."
The server is a high end server with 2.5GB of RAM and there are only 170 users on the server so I don't think there is heavy load on the server.
Any ideas what my problem is? Is it a communication problem? Am I on the right track, am I suppose to be able to telnet from my GC to the Ex2K3 server? If I am suppose to be able to telnet, how do I open port 389 on the Exch2K3 server? I'm running Exchange 2003 with SP2 on a Windows 2003 Server with SP1.
