I experienced this issue on an SBS 2008 server with IIS7. The fix was to enable the “Execute” permission on the CGI and ISAPI modules for the web application, but it was tricky with IIS7. Heres how to do it.
- Open IIS Manager (Start->Run->Inetmgr)
- Select the SMEX Virtual Directory
- Select Handler Mappings
- Find CGI-Exe and ISAPI-dll and select “Edit Feature Permissions” in the action pane.
- Make sure “Execute” is checked and close.
Prior to this, make sure you complete the following other actions (from the Trend Readme):
(1) Install ASP and CGI Role Services
a.Go to the Server Manager.
b.Select Roles and then right-click on the Web Server (IIS).
c.Click Add Role Services.
d.Under Application Development, select ASP and CGI.
e.Click Next > Install.
(2) Allow ScanMail CGIs (if ISAPI and CGI restrictions are
a.Go to the IIS Manager.
b.Select the server node and then select ISAPI and CGI
c.Verify that both cgiDispatcher and cgiCmdNotify are
d.Re-open the ScanMail product console.
