Q185706: FTP-AFTP Gateway Does Not Work with IIS 4.0

Article: Q185706
Product(s): Microsoft SNA Server
Version(s): WINDOWS:4.0,4.0 SP1
Operating System(s): 
Keyword(s): kbbuglist
Last Modified: 19-SEP-1999

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

- Microsoft SNA Server, versions 4.0, 4.0 SP1 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you copy Ftpsvc2.dll from the Sna\System folder to the
Windows\System32\Inetsrv folder and then starting the FTP service, the following
errors will be reported.

  A system error has occurred.

  System error 127 has occurred.

  The specific procedure could not be found.

CAUSE
=====

There are two different Ftpsvc2.dll files, one for Internet Information Server
(IIS) 2.0 and IIS 3.0, and the other for IIS 4.0. Using the IIS 2.0/3.0
Ftsvc2.dll with IIS 4.0 results in the error described above.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server version 4.0. This
problem has been corrected in the latest U.S. Service Pack for SNA Server
version 4.0. For information on obtaining the Service Pack, query on the

MORE INFORMATION
================

In order to use the FTP-AFTP Gateway with IIS 4.0, the IIS 4.0 version of
ftpsvc2.dll has to be copied into the Windows\System32\Inetsrv directory. SNA
Server 4.0 SP1 includes the correct ftpsvc2.dll for use with IIS 4.0 in the
following directory:

\Server\i386\System\Gateway\IIS40

However, after applying the IIS 4.0 version of Ftpsvc2.dll, System Error 127 may
continue to occur. If this occurs, the following files also need to be updated:

  Infocomm.dll
  W3svc.dll

The Ftpsvc2.dll included with SNA Server 4.0 SP1 has a version number of
4.02.0638. The other files listed should be at the same version as Ftpsvc2.dll.

These particular updates to IIS 4.0 are discussed in the following Knowledge Base
