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

ID: Q133721

The information in this article applies to:

Microsoft Network Client for MS-DOS version 3.0
Microsoft SNA Server, versions 2.1, 2.11, 3.0
on the following platforms: NT

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>

where: <SNA_Server> is the Server name in SNA Server Admin, <Incorrect_SNA_Client> is the incorrectly specified computer name of SNA client, and <number> is the service table entry number.

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

In this case, the Windows for Workgroups version of NET.EXE is called first. The Windows for Workgroups version of NET.EXE uses C:\WINDOWS\SYSTEM.INI, instead of C:\NET\SYSTEM.INI. This causes the error to occur.

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
