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]

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.
