Hello All,<BR><BR>I have come across a problem where the writing and retrieving of session data DOES NOT Work if the browser is IE version 6.0 sp 1, and the web server is running windows 2000 server sp 3. <BR><BR>I have since regressed the browser back to IE 5.5 sp2 and the application works. <BR><BR>Other PC's running IE 6.0 without the service pack also work. <BR><BR>It should also be noted that IE6.0 sp1 will work against W2000 with no service packs. <BR><BR>If anyone has any clues as to why this combination fails I would be very grateful. <BR><BR>Cheers <BR>MarkM.
