IIS and false HTTP 404

We started moving the files for some websites we are hosting to a NAS.
We configured IIS5 (Win2KAdv) to have the home directories point to a share.
We target the NAS using its IP address to avoid all name resolution issues.
So, the path looks like \\10.100.225.5\web\my_site\
We also use a valid user for the Connect As settings (we are able to browse
the files from IIS so the user is not the issue). When we first configure
the site, it all works and looks good. But after a while (few hours or
days), random pages start returning a 404 error. This error goes away if we
edit the file directly on the server. It looks like IIS "loses" the page and
then caches the 404 error message?

Any idea?

PS: let me know if you need more information for troubleshooting

thanks a lot

Benoit, did you ever solve this problem? I'm experiencing the same
issue. Thanks, Bob
