SYMPTOMS

When conference participants attempt to join an online conference, and the client is redirected to the local T.120 Multipoint Control Unit (MCU) server by site referral, the following error message may be displayed in the data frame of the conferencing access Web page:
Server Error
Additionally, the Data Conferencing Service may log the following error message in the conferencing participant's "local" T.120 MCU server Application event log:
Source: MSExchangeDCS
Type: Error
Event ID: 8200
Description: An error occured while attempting to add the T.120 MCU server_name.fully_qualified_domain_name to the server topology. Error code: 80070057. Message: The parameter is incorrect.

CAUSE

This problem can occur if a fully qualified domain name (FQDN) with more than 32 characters is entered in the Use Network Name box for remote sites on the "hosting" MCU server; the participating client in the remote site cannot join the data conference and receives the error message in the "Symptoms" section of this article.

When the host server passes the "remote" MCU connectivity information back to the client, a maximum of 32 characters is allowed. If the FQDN exceeds this limit, the referral does not occur successfully.

RESOLUTION

To resolve this problem, obtain Exchange 2000 Conferencing Server Service Pack 1 or later. To obtain a particular service pack for Exchange 2000 Conferencing Server, contact Microsoft Product Support Services. For additional information about the support options available from Microsoft, visit the following Microsoft Web site:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

WORKAROUND

To work around this problem, either move the MCU to a domain with a shorter name or rename the MCU host name so that the FQDN is 32 characters or less.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Conferencing Server. This problem was first corrected in Microsoft Exchange 2000 Conferencing Server Service Pack 1.
