When I try to log into hotmail or any windows live site (using IE), it says the user name or password is wrong. I know it isn't as it works fine on other computers and with other browsers on the same computer.

I found that disabling Norton anti-virus allows be to log in, but I still get problems like clicking log out just refreshes the page.

I'd also had a problem with SP2 not installing. With Norton disabled, it installed ok, but now even with Norton off, I can't log in using IE.

Any ideas? It is a strange problem!
