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:
In addition, a Drwtsn32.log file will be generated in the Windows NT directory. The Drwtsn32.log will contain information similar to the following:
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.
The SNA Server Print service has been updated to correctly free all allocated memory and to reset all related pointers if the StartDoc() fails.
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.
