Terminal Server: Windows cannot access the specified device, path, or file

If you use Windows Terminal Server and you cannot run any applications from your mapped network drives then do the following:

Solution 1
On the Windows 2003 server, go to add/remove windows components, then uninstall the Internet Explorer Enhanced Security component.

Solution 2 (worked for me)
Put the server name in the Trusted Sites zone of IE.

i.e.
\\servername (where your mapped drive is pointing to)

Now all of the .exe's work with no problem...

ExecuteFromMappedDrive to 1.
