GUIMachine Error on startup

Hi-

Recently installed GUIMachine on our dev portal server. The install logs indicated everything was successful. I checked the SQL server and saw the DB was created.

However when starting up GUIMachine, I initially got a "unauthorized error" which was resolved by unchecking anonymous access in IIS.

Now I get a Fatal error indicating "No GUIMachine server was found at specified address" after I click on the Launch GUIMachine URL.

Has anyone seen this error and found a workaround?

Thanks.
