Hi Peter, Sounds vaguely familiar, but I can't pin down what it was that caused the problem. What if you force Basic authentication on the OWA directories? That is to say, remove the checkmarks from the checkboxes of all the authentication types except for basic on the OWA directories at the OWA site.

I have a WAN and various users access an outside SSL site all access was working completely but now the updated browsers (IE6 SP1) freeze part way thru the transactions to the one main site. I have tried various combinations of caching and am now looking at the frames captured in NetMon. What is so different in the latest service pack? I have been told it is my IE6 SP1 plus ISA problem, and that I should call Microsoft. Not yet...I am sure I can lick this one, any suggestions from the gurus.
