Applet issue on Windows 2003 Server?

Strange goings on ...

[jgar]

We have a crossword applet that compiles random crosswords on the fly from a database. The clues are written using asp to a .DAT file, which the applet reads.

The Applet has always worked fine on Windows 2000 server, and on our development machine XP.

But since we moved to Windows Server 2003, the Applet doesn't work any more. The Applet loads into the browser ok, and even creates a crossword, but WITHOUT and clues/answers - as if it is not reading the .DAT file.

Anybody got any clues as to what might be going on?

We'd be very grateful for any insights ...

Cheers

STILL NOT WORKING, but:

If the applet is run on the server, loading the page with the applet directly from the hard-drive (ie not calling the page by a URL), it works.

If the page & applet are called on the server using a URL (localhost, website address or IP address) it doesn't.

Sounds like some sort of permissions issue?

Any ideas how to fix?

see MSDN.

do you have a handler for .DAT extensions?
it is my understanding that every single
extension must be specifically enabled.

UPDATE: Yes, that was it afterall.

We added the .dat file to the MIME list of approved files.
This didn't work though at first.
It was only later when we re-booted the server that the changes took effect.

Thanks for you help!
