We have travel laptops for our attorneys. They aren't tied to our network in any way, because the users have web based apps for whatever they need.
Recently our firm's site (home page) changed. Every PC that I have checked reflects the changes, inside and outside the network. The travel laptops, no matter where they are (connected to our network, connected to our network and bypassing our web filter, at a user's house, etc) will not display the new web page; it displays the old one. I have flushed DNS, cleared all temp files, offline files, history, and cookies, set the network connection to known good DNS servers, updated NIC drivers, have checked for viruses and spyware (nothing was found), and installed Firefox to rule out it being an IE 6 or 7 issue. Firefox gives me the same problem. I have erased all references to the page in the registry as well. As it is happening on more than one laptop and more than one browser type, I ruled out hardware and IE - seems like an OS issue?
The laptops are XP Pro SP2 with either IE 6 or IE 7, fully patched.
Any ideas? Will provide any extra info I can.
