Usually when developing intranet asp.net sites, we usually placed the markup files and css external files
in the server, in that way, all users would have no issue of viewing the site whether using different IE versions.

I don't see any problem with this, maybe you have to coordinate w/ the network manager to check on domain users or something. But basically, there is no issue here.

LOL on liking my signature..I was a teacher before,then stumbled on software development... :-D
