Firstly tell your system admin he is a clot. If he must insist in forcing you to use IE at least make him upgrade to IE7 where you will at least get tabs and little extra sercurity.

Download firefox portable from portableapps.com and save it to a jump drive. Then you can run firefox off the jump drive on any computer at work.
Talk to your sysadmin. He's probably been cracking down on security, and therefore disallowing some programs.
Of course, a more feasible idea here is that using Policies, your System Admin has changed settings for everyone's Internet Explorer to use a proxy server. This is common in the corporate world.

Now in Internet Explorer, Go to Tools -%26gt; Internet Options -%26gt; Connections -%26gt; LAN Settings

If you see proxy settings there, simply make a note of them. Both Opera and Firefox allow you to enter in Proxy settings. Once you do this, you will have no issues browsing the web.
