SYMPTOMS
When an IP data link connection (IPDLC) connection is inactivated while the host sends a bind request, Microsoft Host Integration Server 2004 does not return negative response and the host waits indefinitely.
CAUSE
When an IPDLC connection is inactivated while the host sends a bind request, it is still passed to the Host Integration Server service to open an incoming connection. The Host Integration Server service does not respond to the eXchange Identifier (XID). Therefore, the IPDLC does not respond to the bind request.

MORE INFORMATION
For an inactive connection, the Host Integration Server 2.1 node actually sends an Open (LINK) request message to the DLC to accept incoming connections. However, the Open (LINK) request message then drops any XIDs that the Open (LINK) request message receives on that connection. The IPDLC link service always expects a response to its XIDs because no network connection is involved, but the IPDLC link service does not receive a response.
The Host Integration Server 2.1 node responds to the XID3 with an error if the originator is an IPDLC link service. Additionally, the following error is logged from the IPDLC link service in the application event log:
