Please help. I have installed exchange server 2000 on one of our 2 windows 2000 advance server domain controller (the secondary controller).The exchange seems to be working since I can use outlook pop access and web access to the exchange server.I can also add new users using Active directory user administration.How ever I cannot use the exchange server administration client (also installed on the same windows 2000 domain controller).When i open the administration client and and click the browse button it gives me an error "List of microsoft exchange server computer not available " with an error ID:c10312c8. If i put the name of the server and click ok, it gives me an error"The micorsoft exchange server does not resopnd" error ID "DS_E_COMMUNICATIONS_PROBLEM". Please help. I need to fix this at the earliest. Thanks in advance.
