JSI Tip 10077. NetMeeting does NOT accept incoming calls when Internet Security and Acceleration Server is installed on a Windows 2000 server?

When ISA server is installed on a Windows 2000 server that is running NetMeeting, NetMeeting does NOT accept incoming calls.

This behavior occurs because ISA server and NetMeeting both use port 1710.

NOTE: ISA server is unaffected by this behavior. It operates normally.

NOTE: Only NetMeeting on the ISA server computer is affected. NetMeeting on the ISA server computer can initiate outgoing calls. Clients can use NetMeeting via the ISA server without any problems.
