Hi Peter, There are some authentication issues with the different versions of IE, but I don't quite clear on what it is you're trying to accomplish. Do you have a network diagram anywhere that we can look at so as to get a better idea of what you're trying to accomplish? Thanks!

We use IE6 for data transfer via a web app. The web app actually connects to the remote server then the user starts working, where after 1-2 minuites it freezes. I have 3 domains in a WAN config they share the one Internet access that is thru an ISA server. This ISA server routes back to the 2 remote domains in our WAN, while the ISA server is in the same segment as the first domain. The one remote domain has no problems, the second remote site will only work if the client pc uses IE 5.1 or IE 5.5 The first domain has no problems. I am looking in the ISA logs but don't really know what I am looking for. Could someone suggest the next step?
