Drill Through in Active Report not working (404 Error)

[rvitatoe]

I'm attempting to do a drillthrough in an Active Report and all I am getting is a 404 error going to http://localhost/ibmcognos/cgi-bin/cognos.cgi
Drill Through is working fine in a standard report.
One thing I noticed is that when clicking a standard report drill through, my server name is in the target URL, but the Active Report URL is going to Localhost...  Is there a configuration setting I have wrong somewhere?  Or does IBM just want me to pull out all my hair?
I appreciate any ideas you can throw my way!  Thanks!
