SYMPTOMS

When a client application connected to a remote host over an ISDN bridge closes the connection, one or more of the following may occur:

  • If keep-alives are enabled, the ISDN connection is not permitted to timeout.
  • NETSTAT shows CloseSocket() as established. You must restart the computer to recover from this condition.
  • Without keep-alives, eventually all of the user ports become permanently exhausted. This renders the computer inoperative on the network.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
