Hello,

I'm having a problem with JPG images on our intranet pages which effects around 0.5% of the machines we have... so there must be a simple solution...

The problem is when files are referenced as:

file://server/directory/file.jpg

they do not show, the user does have access rights to the directory etc and if they use another computer they can indeed access this site fine... even as the network administrator with full rights i can not view this website on the effected computers.

all files referenced:

http://webserver/directory/file.jpg

work fine...

Any Ideas?

Could it be that a program was installed which took the file type control away from Internet Explorer?  Often seen; check which program is assigned to deal with JPEGs.

Also, a sad situation has arisen where even JPEGs are a security risk as noted below:

A number of other possibilities come to mind, but think this is a start.  Firewall settings or other 'protections' may also play a role.

Is WindowsUpdate current for the server and/OS/IE?

The apart from windows photo viewer, the only jpeg reading software is corel draw... the website is a local intranet site, thus bypasses the network firewall. Individual terminals do not have a firewall installed. I computer is running the latest version of windows 2k - sp4 with all the latest updates.

Windows 2000 does not appear to be effected by the security scare.

Find a sample .jpg file on your system, right-click to highlight and choose the "open with" option and scroll to Internet Explorer and click "always use this program to open this file type"; close IE and reopen to test.  Otherwise, will check back when I can for other possibilities.
