Login requests pop up

[rharter]

I have built a web site using Frontpage 2003. I have uploaded it to a web
server and everything was working fine. We then added 2 web cams to the site.
I added a java applet to update the web page with the picture, applet was
provided by the camera vendor. I setup up both cameras to ftp a picture to
the server every 10 seconds.

After some unknown period of time, during which everytthing works like it
should, visitors to the site are prompted for a login.

My question is does anyone know why this might be occurring and how do I
stop it from occurring? When I am informed I login to the server and using
the front page extensions reapply the security settings on all directories
and files.

Could this be caused by the ftp'ing of the jpg pictures into the wwwroot
directory?

Thanks in Advance for any help/advice.

Yes, FTP'ing could be a problem. Exactly why is hard to say. It's worth
trying to see if, during this period when the camera viewer dies, you could
try browsing to the file through a web browser and maybe getting a more
detailed error. One of the biggest problems with FP and security settings is
it cannot apply special settings to individual files. It has to do them to
the web site as a whole. It could be that every so often the OS "adjusts"
the permissions on certain files to what it thinks they should be.
Unfortunately, I have little experience with the web-cam end so I'm unsure
of exactly what permissions one may require specifically for it's purpose.

Also, check and see if your camera is using JavaScript or Java. If it's
Java, you may want to see if there is an alternative out there because Java
requires a Java Virtual Machine (JVM) to be installed on the user's
computer. It's a very low percentage nowadays of users that have a JVM
installed and Microsoft is forbidden to ship one with Windows as part of a
settlement with Sun Microsystems (a condition that I think Sun shot
themselves in the foot with).

Something else to look into, is if it's the picture from the webcam that has
the security problem, or some aspect of the Java camera viewer such as a
class file that the viewer is not able to load because of a permissions
issue and not the actual image itself.

Hope this helps,
