The third-party products that are discussed in this article are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of these products.



SYMPTOMS
When you try to join a conference, you do not receive an invitation to join the conference.



CAUSE
This problem occurs when clients who use non-ActiveX browsers (such as Netscape Communications Corporation Netscape Navigator) try to join a conference, and all the octets in their client IP address are three digits (that is, an xxx.xxx.xxx.xxx format). If the client IP address is configured in this way, the Multipoint Control Unit (MCU) does not invite the client to the conference.



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 2000 Server 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.
