SYMPTOMS
After you install Exchange Server 5.5 Chat services on a computer running Windows 2000 Server, you may receive the following error message when you try to administer the Chat service:

Internet Services Manager

The service configuration dynamic link library 'chatcfg.dll' failed to load correctly. The specified module could not be found.



CAUSE
In Exchange Server versions earlier than Exchange Server 5.5 Service Pack 1, Chat runs as an Internet Server Application Programming Interface (ISAPI) extension, and is dependant upon Internet Services Manager for configuration and administration.



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

STATUS
This problem was first corrected in Exchange Server 5.5 Service Pack 1.



MORE INFORMATION
If you apply the latest Exchange Server 5.5 service pack, you update the Chat service to run as its own service; it is no longer dependent upon the Internet Service Manager and you can administer and configure it by using its own Microsoft Management Console (MMC).
