If you are running a presentation broadcast with Chat enabled, you might receive the following Internet Explorer 5.x error:

Invalid syntax error

The page cannot be displayed

The page you are looking for might have been removed or had its name changed.


This is caused when the wrong syntax is used in the ChatURL registry key. You cannot use the Chat URL "irc/chat_server/chat_room" or "irc/chat_server/%23chat_room".

Where Chatserver is the name of the Chat server and Chatroom is the name of your Chat room.


WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).
