Hi, I developed an ASP.Net application using Expression Web and VWD 2005. I deployed it on a W2003 intranet server and all worked fine for few months. The application is used by 6 users, all using windows XP2 and Firefox or IE. Some times one or two computers
had a problem in viewing a treeview menu used by a master page, where the home link was substitued by a word "Skiplink...".
That small difference was only the iceberg peek, because when it appears, whilst is still possible to navigate in the web site, it is no possible to update any information, in the data base (Access data base). The first time I managed to solve the problem
scanning the computers with a Symantec Anti Virus or a MRT utility. After then, the problem appeared more frequently, until when all the computers, including the server, cannot use properly the application being now all stuck. The last day of normal working
I saw my notebook and three other computers passing from a normal operation (it means they were working fine) trough a strange situation as if there were no connection to the site (we use a wireless network) and later it started again with the problem already
visible of the treeView not displaying properly. When using IE the treeview menu is not displayed properly with the hierarchical lines, but each item it has got a kind of image not found icon, and of course no update or insert operation is possible anymore.
I am investigating with many tries and on all computers, but the behavior is misleading. For instance on the server (in localhost) I can use the application normally with IE but I can't use it with Firefox.
I have got the application on my notebook where I developed and maintain it, and it works perfectly using IIS and the web site in localhost. I have got another server at home with W2003 and the application installed to test it, and it works fine till now.
I would say that the intranet server and all the computers at office have got a virus that SAV cannot detect. But I cannot then understand how is it possible on my notebook to run the application from the intranet server, having the problem visible and at
the same time running the application in localhost (from the local site I am maintaining before deplyoing it to the server) without any problem. So either I have got a virus for both applications or not. Any help will be greatly appreciated.

Whenever there are cross-browser issues, the first step is to check for XHTML compatibility of the rendered pages using the W3C tester at
My experiance is that 80% plus of cross-browser issues can be fixed just by fixing the problems indicated by the validator.
