Hey everyone, I have a strange issue.

I setup a Squid proxy at work, I myself and a few others have full access to the net. We also have another proxy server which we are going to be weaving out of the picture soon, my account on that proxy if very limited. I have almost zero access.

My problem is that when I am on the Squid proxy with full access, I cannot do any sort of updates for anything, Windows Updates - No, Software Updates - No.
But when i use the older proxy, where i have zero internet access i am able to do both the Windows and Software updates.

Oh ya, the squid proxy is installed on Ubuntu 12.04 server, and the older proxy is setup on our router.

I am not to sure why this is. Can someone please help me!!!!

Thank you in advance.
