Since swapping from ISA 2000 onto new hardware and fresh install of W2K3 and ISA 2004 (all SP and Patches applied)
Some users have had repeated failed downloads - looks like a timeout issue - however other users (myself included) seem Fine.
We do seem to get more than usual DNS lookup errors on browsing normal pages as well but the downloads is the most obvious effect.
Cant seem to see any answers on the m$ sites or Internet. Im surprised that not more people are having problem.
If we switch back to the old server it all works fine.
