A Google search for "cgi unable to access database in IIS server" pops up lots of information. Maybe something there will point you in the right direction? Or maybe someone here on the Forum has worked with IIS and setting up permissions?
Just a note... are you sure UseMySQLDatabase command is able to find the 'libmariadb.dll' which is required for OpenDatabase to work?
