default printer/login scripts

Greetings,

I would like to change my default printer in Windows
XP. Everytime I just go to printers/faxes and change it
there, and then restart my pc the changes did not take
effect. Its always back to the old default printer. What
would be the best way to change my default printer
without it continuously going back to the old printer?
Would I have to change the login script or something?

Thanks!
Brent
