SYMPTOMS
After implementing chat-specific server extensions to a chat server, the chat server's performance may decline, or it may stop responding altogether. Such server extensions were developed using the Microsoft Exchange Chat Service Software Development Kit (SDK). This kit is available with Exchange Server 5.5 Service Pack 1 (SP1) or with Microsoft Commercial Information Server (MCIS) 2.0.



CAUSE
Implementing a chat server extension that has not been fully tested into a production environment can result in a decrease in chat server performance. In some cases, the chat server may stop responding completely.



WORKAROUND
It is recommended to test any decrease in performance by first temporarily removing any manually-created chat server extensions.



MORE INFORMATION
The Microsoft Exchange Chat Service in Exchange Server 5.5 SP1 and MCIS 2.0 include two sample server extensions, Channel Transcription, and Profanity Filter. Activating any server extensions on the chat server will result in some decrease in server performance. The sample server extensions that were shipped with Microsoft Exchange Chat Service were thoroughly tested for optimized performance. Consequently, they may only cause minimal decrease in performance.

Using the Microsoft Exchange Chat Service SDK, you have the ability to develop your own server extensions.
