Whether you are upgrading to a newer version of the Secure Ad Hoc Transfer (SAT) module or upgrading EFT Server, consider the following information:
It is very important that SAT have the same version of SFTPCOMInterface.dll that the EFT Server to which SAT is connecting is using. Upgrading EFT Server might require also updating the SFTPCOMInterface.dll for the SAT module.
If EFT Server and SAT are on the same computer, then the upgrade process for EFT Server will register the new .dll on the computer and will be used by SAT; however, in this case the IIS service must be restarted. This is important so that ASP.NET (hosted by the "aspnet_wp.exe" process) will release any references to the existing COM object and reload the new one.
By default, SFTPCOMInterface.dll is stored in the EFT Server installation directory and in C:\Inetpub\EFTAdHoc for the SAT module.
To restart IIS
Click Start > Run.
In the Run dialog box, type iisreset, then press ENTER.
A command prompt appears, IIS is reset, and then the screen closes.
