SYMPTOMS

When you try to start a video call by using Microsoft Office Communicator on a computer that is running Windows Server 2008 or Windows Vista, the video call may fail.

This problem may occur when a third-party legacy Transport Driver Interface (TDI) filter driver is installed on the computer. TDI filter drivers may be used by some antivirus software.

CAUSE

When there is a third-party legacy TDI filter driver installed on a computer that is running Windows Server 2008 or Windows Vista, the system receives error code WSAEADDRINUSE (10048) when the system tries to bind the socket for the first time. When the system tries to bind the socket for the second time, it receives error code WSAEINVAL (10022). This series of events may cause Office Communicator to be unable to bind to a specific local endpoint and to be unable to start the video call.
