Thanks. Tried that already, no go. There is one thing that changed, for various reasons I no longer remember, I had the internal port still at 80 instead of the standard alternative port (I think I was trying to get MSN IM to work). I recently changed it to the alternate port because I have a new IM server on the inside. I changed the IIS and the ISA to reflect this. Worked fine for a day and a half, today stopped working with the below symptoms. I tried to back all the way to where I was days ago, and now it won't let me change the IIS back to 80, says address already in use. I can get in with 9999, but it prompts for logon. The OWA has ceased working altogether. Starts to draw the 2 frames and then says page can not be displayed in both frames. I suspect I messed up my destination set and I can't remember if I had the external or internal address (or both) in the web set.

Including OWA, etc. Not sure what I did but I now get prompted for 2 web sites that were anonymous access and I get this error even after providing credentials: The server has detected a proxy chain loop. This condition might indicate a configuration problem in a proxy server. Anyone have a thought on where I should be looking for this? Thanks.
