SNA Error 505: The Host Terminated the Connection Used...

• Microsoft Network Client for MS-DOS, version 3.0
• Microsoft SNA Server for Windows NT, versions 2.1, 2.11 and 3.0

SYMPTOMS

When you use Microsoft Network Client for MS-DOS and Microsoft SNA Server 2.11 or 3.0 DOS Client, the 3270 terminal emulator may display communication status 505 and then stop responding (hang).

CAUSE

The incorrect computer name is called up during network initialization. SNA DOS Client traces show the following:

   ... ... ... ... Remote box? <SNA_Server>:<Incorrect_SNA_Client>
   ...
   ... ... ... ... STAB entry <number> for box <Incorrect_SNA_Client>

This situation occurs when both the MS-DOS-based and Windows-based clients are in the path. For example, your AUTOEXEC.BAT file contains the following:

   PATH C:\WINDOWS;C:\NET;C:\DOS;C:\;
   NET INITIALIZE
   NET START

The SYSTEM.INI contains the following entry for the SNA Client's computer name:

   [Network]
   ComputerName=<SNA_Client>

RESOLUTION

Use one of the following two methods to ensure the correct version of NET.EXE is used:

• Specify the complete path in the AUTOEXEC.BAT file. For example:

        C:\NET\NET INITIALIZE
        C:\NET\NET START
  

  -or-

• Remove Windows from the Path statement. For example:

        :NET
        PATH C:\NET;C:\;
        NET INITIALIZE
        NET START
