Symptoms

Consider the following scenario. A Microsoft Host Integration Server 2004 client is installed on a server that has Microsoft Windows Server 2003 Terminal Server enabled. The first user logs on to the terminal server. The first user can successfully run an SNA application through the Host Integration Server 2004 client. An example of an SNA application is a 3270 emulator. Successive users log on to the terminal server, and the successive users try to run an SNA application. In this scenario, the successive users receive the following error message:
SnaBase failed to start
When this problem occurs, an event that resembles the following is logged in the Application log:

Event Type: Error
Event Source: SNA Base Service
Event Category: None
Event ID: 567
Date: Date
Time: Time
User: domain\username
Computer: Computer name
Description:

The Drwtsn32.exe file may be the default debugger for the terminal server, and the Drwtsn32.exe file may be configured to create a User.dmp file. In this case, the stack output that appears in the User.dmp file resembles the following information when this problem occurs:
