Configure Downstream Leased SDLC Connection Causes Error 3992

ID: Q151205

The information in this article applies to:

Microsoft SNA Server, version 2.11 SP1
on the following platforms: NT

SYMPTOMS

You will get the following error when you configure a Downstream Leased SDLC connection:

Error: 3992

Leased SDLC connections cannot support Incoming Calls.

Leased connections do not require either end to initiate the
connection, therefore both ends treat the connection as
Outgoing Calls only.

CAUSE

SNA Server 2.11 Service Pack 1 included a fix that changed the default Allowed Directions for Downstream Connections to Incoming Calls.

For additional information, please see the following article in the Microsoft Knowledge Base:

Q139423 Downstream Connection Should Default to Incoming Calls

Service Pack 1 does not check to see if a SDLC connection is Leased before defaulting the Allowed Directions setting to Incoming Calls. Error 3992 results because Leased SDLC connections cannot support Incoming Calls.

WORKAROUND

Use SNA Server Admin to create a new SDLC connection specifying Remote End as Host System. After you configure this connection, go back into the Connection Properties for this connection and change Remote End to Downstream.

SNA Server Admin has been updated to check whether a new downstream SDLC connection is Leased before defaulting the Allowed Directions setting to Incoming Calls.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SNA Server version 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
