SYMPTOMS
You may experience connectivity problems when you run the following types of applications on Microsoft Host Integration Server 2000 or Microsoft Host Integration 2004 multi-homed client computers:
 * Advanced Program-to-Program Communications (APPC)-based applications
 * 3270 emulator-based applications

These connectivity problems may occur over time if the following conditions are true:
 * The SnaBase service is not periodically restarted.
 * Host Integration Server has the Named Pipe transport disabled.

The specific symptoms that you experience depend on the type of client that you are running. For example, if you run a Transaction Integrator (TI) application, the following Error event may be logged in the Application log: Event Type: Error

Event Source: COMTI

Event Category: General

Event ID: 102

Date:

Time:

User:

Computer:

Description: (102) Transaction Integrator reported the following exception to the client:

Component:

Method:

Exception description: (1407) The COM Transaction Integrator LU 6.2 transport failed to allocate a conversation. Do not retry until status of host LU < > is corrected.

If you collect a full internal trace for the SnaBase service on the multi-homed client computer that is experiencing this problem, connection failure information appears in the trace. The following trace information shows that failed connection attempts are incorrectly targeted back to the client computer itself instead of to the Host Integration Server computer. Destination is REMOTE Using ltab 03A90104, index 1 for pipe Release shrmutx before calling OpenConnection Opening a connection to service 2717 srvtyp =27 Local 65, Remote 65 Starting from transport 1, dwPriority 0 Found common transport 1, type 64 Trying transport 1, type 64 Local address: 0.0.0.0:1290 Trying to connect to: 192.168.244.33:0 connect failed, error 10049 Trying to connect to: 192.168.244.65:0 connect failed, error 10049 Trying to connect to: 192.168.244.63:0 connect failed, error 10049 Trying to connect to: 192.168.244.62:0 connect failed, error 10049 Trying to connect to: 192.168.244.61:0 connect failed, error 10049 Trying to connect to: 192.168.244.60:0 connect failed, error 10049 Trying to connect to: 192.168.244.59:0 connect failed, error 10049 Trying to connect to: 192.168.244.58:0 connect failed, error 10049



CAUSE
This problem occurs because the SnaBase service contains logic problems that cause service table entries to be populated incorrectly on multi-homed client computers. The service table entries are populated with the client IP address instead of the server IP address.
