This is working in Windows 2003 AD Domain. This is xp workstation, after the user logon to the domain, he opens windows explorer > my computer, he can see a list of mapped drives. If he double-click the mapped drive on the left pane, he would see all the contents appear on the right pane. But, if he double-click the mapped drive on the right pane, he can't open some of the mapped drives, indeed, an "Open with..." dialog box appears - with the choices on open with adobe reader, notepad, Internet explorer, etc.
If I run net use in command prompt, some mapped drives are found disconnected, why?
