The information in this article applies to:

  • Microsoft Windows NT Server 4.0 Terminal Server Edition
  • Microsoft Windows NT Server 4.0
  • Microsoft Windows NT Server, Enterprise Edition 4.0
This article was previously published under Q235602

SYMPTOMS

Client computers may report problems connecting to Microsoft Windows NT Server-based computers, and any of the following error messages may be displayed on the client computers:
  • Error 1723: The RPC server is too busy to complete this operation.
  • The RPC server is too busy to complete this operation.
  • Error 53: The network path was not found.
  • Error 51: The remote computer is not available.
Services.exe may also cause an access violation and generate a Dr. Watson log.

CAUSE

This behavior occurs because a series of events causes a thread in the browser code to gain access to an invalid memory location or to corrupt a valid memory location.
