When you attempt to use the Microsoft Exchange Server Administrator program to create a newsfeed on a Windows 2000 Server computer, and you select a very large active file to import, the newsfeed may not be created and the directory service may stop responding (hang).


When using the Microsoft Exchange Server Administrator program to remotely manage a large (1200 or more members) Distribution List (DL), after a long wait the user may encounter the following message:

The Microsoft Exchange Server computer does not respond. MSExchange Directory ID NUM DS_E_COMMUNICATIONS_PROBLEM.

Typically, this appears after you try to add or remove a member. If Admin.exe is on the Exchange Server, this behavior does not occur. Only if the Exchange 5.5 server is on Windows 2000 and Admin.exe is running remotely is this an issue.


When you specify a very large active file to import, the Administrator program may attempt to send a large amount of data to the directory using a single remote procedure call (RPC). If the Administrator program attempts to send too much data, Windows 2000 Server prevents the connection from being established. Because the Administrator program cannot write to the directory, it cannot create the newsfeed.


To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

To prevent this issue from occurring, select a smaller active file to import.


Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
