Mcafee webshield When I access Mcafee Webshield e250 through the browser, it gives me: Internal Server error

Error 500 to 504 are usually nothing to do with your system, they are errors created by the server you are trying to connect to.

Introduction
A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.

Wow, not sure how this listing got filed under a Network Firewall, other than the "Appliance" keyword, but here goes...

Your heating element is 1 of basically 3 parts that all need to function to get the heat going, the element is 1, the relay is 2, and the controller is 3. If you've replaced the element, then it must be the relay or controller of course.

CAREFULLY use a multimeter to test the voltage of the socket the elements connect to while they should be heating. If there's no voltage there, follow the socket's wires to a small box (probably 1-2" square) with 1-2 other wires coming from it. Test the voltage at the 2 other wires, or if there only one other wire, at the other wire and the element's black wire. If there's voltage there, it's probably a bad relay, which is much cheaper then the controller. If there's no voltage there, then it's the controller.

check if your local network is not being blocked by macaffe's firewall.

here are instructions on using the Mcafee Removal tool.

Write a nice letter to the IT staff, and explain why you would like this unblocked. I am sure if you are nice anough, they will remove the block... OK so I am sure they won't. There should not be any way around this if the admin has done there job. Just wait till you get home, do all of your homework, then visit myspace from your home pc, and do schoolwork while in school.

Try starting up in safe mode by pressing F8 a few times during boot to get the bootup menu. Select safe mode by itself. If you have system restore on then you can try to revert back to right before you installed mcafee. Your machine probably created a restore point right before the software installed. This would be the easiest way to get around this issue. Another way would be to boot into safe mode then go to start -> run and type msconfig then press enter. The System Configuration Utility should come up. Go to the startup tab and uncheck all mcafee related items. Click OK then reboot. McAfee won't start on boot and crash your machine and you can then uninstall it. Be careful with this step though as you could make things worse by unchecking the wrong startup items. Its best to try and revert to a restore point first.
