SYMPTOMS
When you send a LISTX command to a Microsoft Exchange Chat Service computer, the server may unexpectedly end the connection to the client. When this occurs, a list of chat rooms and their topics may be displayed, but it is a very incomplete list.



CAUSE
This problem occurs when the results of the LISTX command must be truncated and the output buffer overflows while the partial listing is being sent to the client.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

Component: Chat Service



STATUS
