Microsoft IIS configuration issues
Fix Microsoft IIS configuration issues as follows:

3 Create the virtual SAXT folder again, pointing to the same SAXT installation folder, and the same SAXTApplicationPool for the Application Pool property.
4 Select SAXT in Microsoft IIS.
5 Go to Authentication and perform these actions:
Enable Windows Authentication.
Enable ASP.NET Impersonation.
Disable Anonymous Authentication.
Disable Basic Authentication.
6 Restart Microsoft IIS and restart the server machine.
Open the SA2001.log file in a text editor such as Notepad. This should contain an entry with an error message that was received from the application. If there is nothing there, check for errors in the system’s Event Viewer, normally accessible from Control Panel > Administrative Tools.
