Forefront TMG reports only show IP addresses for SecureNAT

Hi,

I'm aware that by default that TMG will only show the IP addresses of traffic from SecureNAT clients.  I have tried both the 'LogHostnames' product, and a script I found here: http://support.microsoft.com/kb/980723
Which both fix the site names displayed when I do a URL query, but it doesn't fix the reports which all still just show IP Addresses.

I can't seem to find any information relating to this problem, as it seems that after either applying that script or installing LogHostnames it usually would fix both the query URL and the reports?
