Hello, This is a very weird problem. I just got more IP addresses from my provider, and OWA doesn't come up all the way any longer. This is very confusing. All the same publishing rules still apply, and I also configured the main ISA Server to use dedicated listeners for the Web stuff which didn't work, so then I tried using All IP's for the listeners. Still, the same result. I am just running out of options here, and I just don't understand how adding IP's can cause something like this to happen: The page loads fine - still prompts for the Users Name, Password and Domain, then allows them to proceed further, then loads & populates the treeview, then it shows all the folders, and then just stops - with it just showing "loading..." in the window pane on the right side of screen. Everything else, is there - like normal - it just doesn't show the message list. ALSO, the web page generates an error. When you double-click the Exclamation Point Icon in the lower left-hand corner of the browser window, you get the following error: "Problems with this web page might prevent it from ... blah blah..." And the Specific Error Code is: Line: 1713 Char: 3 Error: Unknown name Code: 0 URL: http://outlook.anderson.net/exchweb/controls/ctrl_View20.htc Could somebody let me know, if they have seen this before - and what the fix may be? I am running Windows 2000 Server SP3, with ISA Server SP1. Please help! - Thanks, Mike
