I would apreciate some help.

I have a proxy server which is connected to pc's and iMac's.

The users can use the PC's without any problems, however when the same users use the iMac's to surf the internet, they cannot.

I have configured the iMac's correctly to access the internet. All the settings are correct, and I (with administrative privilages) can view pages.

So, what is the problem?

If you need more info, just ask.

Proxy server version? (I presume MS?)
Mac OS version?
What OS is the server running?
DNS on the LAN?

Are you saying that you can login from the MAC's with Admin priv's and access the internet but a regular user cannot?

Hello Joe:

"Quite sure that I can access the internet and the students cannot."

I need to be really clear on this:
From a students machine YOU can login with admin priv's and access the net. From the SAME machine a student can login (with their priveleges) and cannot access the net?

That is correct.

The students have access to the PC's and the mac's.

Each student has access to the internet, under the 'Web Access' group I have set up.

Little Sid can access the internet on the PC's, but not on the Mac's.

I can access the internet on the PC's and the Mac's.

I wish that I could give you the 'point-and-click' answer. I cannot. Too many variables. But I can point you in the right direction.

You have, obviously, a permissions problem.

When a non-administrative client tries to access the net do you get an error or does the progress bar just 'sit there'?

To troubleshoot this I would start from scratch on the MAC clients. Check ALL of your assumptions and try various things to prove/disprove your theories:

If you add a MAC client to the admin group can you now access the internet?

Re-read the Proxy Help section on Web Proxy. Remember that MAC clients authenticate differently on NT.

Are the MAC users also part of another group with different permissions?

For future reference on Proxy Server here is the most useful reference I have seen: http://proxyfaq.networkgods.com

Good luck and I hope I was of some help.

Things to check:

When a student logs into a MAC, and starts a browser, are the proxy settings correct? (Don't just say 'of course' -- look at them.) If you are auto-detecting proxy settings, or trying to configure from a file, the permission problem may be on that file.

If you turn off all restrictions in Proxy, can the students on the MACs get in?

If you explicitly put a student's login in Proxy's allow list, can the student then get in? (The student on a MAC may not be getting the group rights for some reason.)

Pick a student. Set that student's account up for failure auditing. Turn on auditing for your whole \winnt directory and subdirectories. Try to log that student in from a MAC, and check the event viewer to see where hefailed. If it is a file, fix the permissions to give access to the group.

Good luck.
