SYMPTOMS
========

After you start SNA Server Manager, if you close Server Manager before the
domain is fully opened (that is, while the hourglass is displaying before the
configuration information appears), an access violation can occur in Mngcli.exe.
An entry in <Ntroot>\Drwtsn32.log will be created as follows:

  Application exception occurred:
     App: mngcli.dbg (<process ID>)
     Exception number: c0000005 (access violation)

  [...]

  function: EnterCriticalSection

  FAULT ->77f4704a f0ff4204    lock   inc dword ptr [edx+0x4]
  ds:0068e923=????????

CAUSE
=====

Server Manager attempts to close the domain that was already closed.

RESOLUTION
==========

To work around this problem:

  Do not close Server Manager until the domain has been opened and the
  configuration information is displayed.

With this hotfix applied, Server Manager checks to see whether the domain is
already closed before attempting to close it.
