Having a major issue and this all seemed to stem after I tried to remove a HTTPS Inspection website (dropbox.com) from the list.  it looks like between my two appliances they are no longer updating any URL categorys as well.

When I click into ' Configure HTTPS Inspection ' and clikc the destionation Exceptions tab I get "Forefront TMG cannot load the property page".  I also notice now when I go into Monitoring > Configuration > that my two servers show Last Updated - 11/29/1999 7:00 PM .  

Ran the BPA and it does come back with:

-HTTPS Inspection configuration not loaded error alert was signaled 1 times.

-The secure channel to the domain controller cannot be verified

-The security descriptor of a logging folder does not grant sufficient rights

-The upload new configuration to services failed error alert was signaled 10 times

-The upsteam chaining credentials error alert was signaled 1 times

This thing worked totally fine up until I tried removing that one domain name.  Any suggestions as to what happened and how to fix?

Thanks in advance,

Jordan

Hello Jordan,

Try to run installation from the TMG DVD/Image and use repair mode.
