The information in this article applies to:

- Microsoft Windows NT Server versions 4.0 SP4, 4.0 SP5, Terminal Server Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

When a RAS client disconnects from a RAS connection, some RAS ports may become
unavailable.

CAUSE
=====

This problem can occur when a RAS client disconnects a RAS connection. When this
happens, a port status mismatch may occur between Rasman.exe and Rassrv.exe.
When this mismatch occurs, the port event handler is not called and the port is
not reinitialized. Because of this, the port becomes unavailable.

RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
correct the problem described in this article and should be applied only to

testing at a later time, to further ensure product quality. Therefore, if you
are not severely affected by this problem, Microsoft recommends that you wait
