TN5250 Clients Cannot Connect to a Specific AS/400

 Last reviewed: April 17, 1997
Article ID: Q159627
The information in this article applies to:
  • Microsoft SNA Server for Windows NT, version 3.0

SYMPTOMS

TN5250 clients that are connecting to an SNA Server that has connections to multiple AS/400s cannot specify which AS/400 to connect to.

CAUSE

The TN5250 RFC (RFC 1205) does not include a specification that would allow TN5250 clients to specify an AS/400 to connect to. Therefore, the TN5250 service included with SNA Server 3.0 was not designed to support a mechanism that would allow TN5250 clients to connect to a specific AS/400.

RESOLUTION

To work around this problem:

  1. Set up multiple computers running SNA Server and running the TN5250 service. Each one must have a connection to a different AS/400.

  2. Configure the TN5250 client(s) to connect to the TCP/IP Address or Host Name of the computer running SNA Server that has a connection to the AS/400 that the client(s) wants to connect to.

NOTE: Only one instance of the TN5250 Server service can be used on a computer running SNA Server. To support this resolution, multiple computers running SNA Server must be used, each running a different TN5250 Server service.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
