The disconnected session could be caused by a remote server problem or because an inbound connection limit has been reached on the remote server.

Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, How to troubleshoot network connectivity problems.

  • Adjust the inbound connection limits on the remote server.
