SYMPTOMS
When you dynamically add a host connection to an active Microsoft SNA Server service (Snaservr.exe), the host connection may show a Pending status and may not become active. When this problem occurs, an event that is similar to the following may be logged in the Application log: Event ID: 56

Description: Connection  failed: XID rejected by remote computer.

The problem only occurs if you have defined the dynamically added host connection by using a Network name value or a Control point name value that is eight characters long.



CAUSE
The SNA Server service incorrectly truncates the Network name value and the Control point name value to seven characters when the SNA Server service parses these values for a dynamically added host connection.

MORE INFORMATION
To determine whether you are experiencing this problem, you can use the SNA Trace Utility (Snatrace.exe) to capture the activation sequence for the new host connection. The following example shows how to identify the problem.

Assume that you add a new host connection to an active SNA Server service by using the following values:

A Data Link Control message trace on the SNA Server service that captures the activation sequence for the new host connection would include the following Send XID (SXID) message: DLC  01020300->06160000 DLCST SXID DLC DLC   Header at address 01194480, 1 elements DLC  1AFF000C 10110D00 00000700 01006409     <..............d.> DLC DLC   Element at address 01B82C84, start 14, end 117 DLC  326805DF FFFF0000 B0041000 00000000     <2h..............> DLC  00010B00 00010900 00000007 00103700     <..............7.> DLC  23110C08 04F0F5F0 F0F0F00F 06D4E240     <#....050000..MS@> DLC  C84BC94B E2C5D9E5 C5D90908 F0F0F0F0      DLC  F0F0F013 11031000 10F0F0F0 F0F0F0F0     <000......0000000> DLC  F0F0F0F0 F0F00E10 F4C1D7D7 D5E3C5E2     <000000..4APPNTES> DLC  4BE2C4D3 C3E3C5E2                        The last fifteen bytes of the trace data includes the fully-qualified control point name (Network name.Control point name) that is configured in the properties of the host connection. In this example, the trace data has the following value:

APPNTES.SDLCTES

The configured Network name value and Control point name value are truncated in the XID message that is sent to the host system.

Note The Trace Viewer that is used to view Host Integration Server trace files displays an EBCDIC period (.) as an ASCII uppercase K.
