256986 Description of the Microsoft Windows Registry



SUMMARY
Instant Message Polling and Fixed Port callback delivery are new connection features that are available in Exchange 2000 Service Pack 1 (SP1). You can use these features to configure connections between a server that is running Exchange 2000 Instant Messaging Service and a client computer that is running either Microsoft Windows Messenger or Microsoft MSN Messenger, even if the server or the client is protected by a firewall.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

By default, the Instant Message Polling feature and the Fixed Port callback delivery feature are not turned on on a server that is running the Instant Messaging Service. If you are the server administrator, you can use Registry Editor to turn on Instant Message Polling support:  Click Start, click Run, type regedit, and then click OK. Locate and then click the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\InstantMessaging

 Double-click the PollSupport value, and then type 1 in the Value Data box.

When you set the PollSupport value to 1, Instant Message Polling and Fixed Port callback delivery function correctly.

For more information about server and client registry settings, see the &quot;Instant Message Polling and Fixed Port Callback Delivery&quot; white paper. To see this white paper, visit the following Microsoft Web site:
