Q172291: Snacfg.exe Does Not Support Omission of LOCALBLOCKNO

Article: Q172291
Product(s): Microsoft SNA Server
Version(s): WINDOWS:3.0,3.0 SP1
Operating System(s): 
Keyword(s): kbenv kbnetwork

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 3.0, 3.0 SP1, on platform(s):
   - the operating system: Microsoft Windows NT 
-------------------------------------------------------------------------------


SYMPTOMS
========

When you configure an SDLC connection using Snacfg.exe, if the LOCALBLOCKNO (the
first three digits of the Local Node ID, also known as the IDBLK) value is
omitted, you receive the following error message:

  The first three digits of the Local Node ID are invalid. These digits, also
  called the Block Number, can be any three hexadecimal digits except 000 or
  FFF, which are reserved.


CAUSE
=====

Snacfg.exe does not set the SDLC connection "fSdlcLeased" flag based on the
specified link service. If this flag is not set, the validate routine in
Snacfg.exe does not recognize the connection as being associated with a Leased
SDLC link service and considers the omission of the IDBLK as invalid.

RESOLUTION
==========

Snacfg.exe has been corrected so that it now verifies the specified link service
is SDLC and Leased. If the link service meets both these criteria, the IDBLK
value can be omitted.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 3.0 and 3.0 Service
Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0
U.S. Service Pack. For information on obtaining this Service Pack, query on the
