FTP-to-AFTP Gateway Program Does Not Function with IIS (149123)

SYMPTOMS

The SNA Server FTP-to-AFTP gateway program, included with SNA Server version 2.11 Service Pack 1, does not work with the FTP Publishing Service that comes with the Microsoft Internet Information Server (IIS) version 1.0. When you try to install the SNA Server AFTP gateway on the same computer that the FTP Publishing Service installed, you will get the following error message:

FTP Server Not Installed!

FTP Server is not installed on this computer. Please install an FTP
Server before running this setup program.

CAUSE

During the installation of the FTP-to-AFTP gateway, the executable Ftpregsu.exe searches the registry for the following registry key:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\FTPSVC

This program modifies the ImagePath value to point to the Gateway.exe file.

FTPREGSU displays the above error because the FTP Publishing Service uses the following registry key:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSFTPSVC

instead.

The FTP Publishing Service DLL file shipped with IIS (Ftpsvc2.dll) is different than the FTP Server DLL file that is shipped with Microsoft Windows NT version 3.51 and the SNA Server FTP-to-AFTP gateway (Ftpsvc.dll). Renaming the DLL file from Ftpsvc2.dll to Ftpsvc.dll has no effect on the problem.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SNA Server versions 2.11 and 2.11.sp1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
