When I log on to Myspace.com with my correct user name and password, it kicks me back to the log on page again. I can log on through other PCs on my network through the same firewall. There's got to be an Internet Explorer setting that will allow it. I installed Firefox on the problem PC and it doesn't have the same problem.
Any suggestions?

Try going to the Tools menu and selecting Internet Options. Find and click the button to reset Internet Explorer default settings. That will undo any obscure setting change that might be blocking it.

That's what I thought too, but it didn't change anything. I don't have this problem with any other site other than Myspace.

Thanks for the suggestion.

I don't know what MySpace.com runs on but, perhaps you need to re-install something to allow the code to work, such as ActiveX or Java support. For example, are the other PCs on your network running Java Runtime? If so, try downloading and installing (or re-installing) that on the problem PC - you can get it from www.sun.com.
