I did add IE Browser Security Update within the time frame of the incident. I was looking over this Q-Artile Q307347, that explains AddFrontEndHttpsHeader and this problem was corrected in ISA Server 2000 SP1. My Question, do I need to re-install ISA Server 2000 SP1 again? Can anyone help me verify that SP1 adds this entry to the registry with SP1? I do not have this DWORD in my ISA box am I running down the wrong rabbit hole? 1. Locate and click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3Proxy\Parameters 2. Create a new DWORD value that is named AddFrontEndHttpsHeader , and then give this new value a data value of 1.
