TITLE :Print Server Application Exception in Function AimOpenPrinter
PRODUCT :Microsoft SNA Server
PROD/VER:WINDOWS:3.0,3.0 SP1
OPER/SYS:
KEYWORDS:kbnetwork
======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:
- Microsoft SNA Server, versions 3.0, 3.0 SP1
-------------------------------------------------------------------------------
SYMPTOMS
========
The SNA Server Host Print service may generated an application exception when
attempting to start a configured print session in SNA Server Manager. An error
similar to the following will be logged in the Windows NT Application Event Log
when the application exception occurs:
Event ID: 4097
Source: DrWatson
Description: The application, exe\snaprint.dbg, generated an application
error.
The error occurred on <date> @ <time>. The exception generated was
c0000005 at address 01002308 (AIMOpenPrinter).
In addition, a Drwtsn32.log file will be generated in the Windows NT directory.
The Drwtsn32.log will contain information similar to the following:
Application exception occurred:
App: exe\snaprint.DBG (pid=<process id #>)
When: <date> @ <time>
Exception number: c0000005 (access violation)
CAUSE
=====
When starting a print session, the Print Server attempts to open a connection to
the configured printer by issuing a StartDoc() call. If the StartDoc() call
fails, the print server was not properly setting all related pointers to NULL,
causing the application exception to occur.
In a reported occurrence of this problem, the StartDoc() call failed because the
print server was not able to connect to the TCP/IP address of the remote printer
that the print session was configured to use. There may be other reasons that
StartDoc() fails that result in the same application exception.
RESOLUTION
==========
The SNA Server Print service has been updated to correctly free all allocated
memory and to reset all related pointers if the StartDoc() fails.
STATUS
======
Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0
Service Pack 1 (SP1). This problem was corrected in the latest SNA Server
version 3.0 U.S. Service Pack. For information on obtaining this Service Pack,
