HTML HELP hh.exe wont let me open a .chm file from a networked drive- getting Action canceled when doing so

Machine : Dell 340 Precision
O/S: Win 2K 5.00.2195

We have got a lot of .chm files stored on our network drives so development and documentation can interact.

So far all is fine - You doubleclick one of those .chm files, hh.exe starts and displays the content in Windows "HTML HELP".
Only - for one of our developers this only works when copying the file to his local drive on his workstation.

If he does it remotely - HTML HELP winds up with the following message:

----snip-----

Action canceled
Internet Explorer was unable to link to the Web page you requested. The page might be temporarily unavailable.

Please try the following:

Click the  Refresh button, or try again later.

If you have visited this page previously and you want to view what has been stored on your computer, click File, and then click Work Offline.

For information about offline browsing with Internet Explorer, click the Help menu, and then click Contents and Index.

To rehash again.
Choose random .chm file.
Try opening it from a networked drive results in mentioned error.
Copying it to a local drive and opening yields the desired result.i,e, it works.

I suspect a permission problem, but changing security settings from within hh,exe as well as Internet Explorer and setting them to "low" didnt change much.

Other than that I m not sure where to go look for clues.

Any hints or even a solution to this appreciated ;D
