The information in this article applies to:
- Microsoft SNA Server, versions 2.11 SP2, 3.0 SP1
-------------------------------------------------------------------------------
SYMPTOMS
========
After applying Microsoft SNA Server, version 2.11 Service Pack 2 (SP2) or SNA
Server, version 3.0 SP1 on a system that's using an Attachmate ISCA adapter for
an SDLC connection, the SNA Server service fails to start, reporting the
following error:
The specified image file did not have the correct format.
It did not have a proper e_lfarlic in the MZ header.
CAUSE
=====
These Service Packs contain a corrupt version of DCASYNC.SYS. This file is the
driver for the Attachmate (DCA) ISCA SDLC card used by the DCA SDLC link
service. Upon starting, the SNA Server service attempts to start the link
services installed on the system. The above error is being returned from the
DCASDLC link service.
RESOLUTION
==========
DCA X.25 link service uses the same driver as the DCA SDLC link service. Only
the version in the DCASDLC directory is corrupt. The copy of DCASYNC.SYS in the
DCAX25 directory can be used for the DCA SDLC link service.
A working copy of the driver is located in the following directory on the Service
Pack compact disks:
<CD>\SERVER\I386\SYSTEM\HWSETUP\DCAX25
The DCASYNC.SYS file can be copied from there to the following locations on the
server:
<snaroot>/system
<snaroot>/system/hwsetup/dcasdlc
STATUS
======
The versions of SNA Server 2.11 SP2 and SNA Server 3.0 SP1 on the Microsoft FTP
site have been updated with the correct version of this driver.
