APPLIES TO

  • Microsoft Chat 2.0



This article was previously published under Q171664

SYMPTOMS

When you attempt to send a file to someone through a proxy server (a server on a local area network that lets you connect to the Internet without using a modem) using Microsoft Chat, you may receive the following error message:

Transfer timed out. File transfer failed.

When you click OK, the file transfer is canceled.

CAUSE

This problem can occur if either of the following circumstances exists:

  • The proxy server is not configured to allow connections over ports 7011 and higher.
  • Microsoft Chat is using all the available ports on the proxy server higher than port 7011.


RESOLUTION

To resolve this issue, use one of the following methods:

  • Have your network administrator enable ports 7011 and higher on the proxy server.
  • Quit and restart Microsoft Chat to reset the ports it is using.


MORE INFORMATION

Microsoft Chat uses ports 7011 and higher for file transfers. When these ports are disabled on the proxy server, Microsoft Chat holds file transfers until they time out.

This problem also occurs if the number of file transfers exceeds the number of available ports higher than port 7011. Once a port is used for a file transfer, it is no longer available to Microsoft Chat. If there are no more available ports higher than 7011, file transfers time out until you quit Microsoft Chat and restart it.
