Default APPC Are Not Resolved Correctly for OS/2 Clients (153411)
The information in this article applies to:
- Microsoft SNA Server 2.1, when used with:
- the operating system: Microsoft Windows NT
- Microsoft SNA Server 2.11, when used with:
- the operating system: Microsoft Windows NT
This article was previously published under Q153411 SYMPTOMS
APPC applications using the Microsoft SNA OS/2 client that make a call to a
default local LU or remote LU may fail.
CAUSE
The TP_STARTED verb is passing a local LU alias of all zeroes. Therefore
the APPC library goes into default LU processing, which is to query the
user record from the SNA server. For OS/2, this is done by calling the
sepdcrec()function. The wrong information is being returned on this call,
which is causing the APPC library to believe that the LU alias for this
user is a one byte value of 0x01. When the APPC library tries to use this
as the local LU alias, the SNA Server rejects it.
The OS/2 APPC library's support for extracting a local LU for a particular
user was broken when the OS/2 DMODs sepdcrec() processing was changed to
use RPC calls to query the server.
STATUS
Microsoft has confirmed this to be a problem in Microsoft SNA Server
versions 2.1 and 2.11.
This problem was corrected in the latest Microsoft SNA Server 2.11 U.S.
Service Pack. For information on obtaining the service pack, query on the
