^ ditto, i am having the same problem. i am running on vista home premium, but method 2 had no effect. my PC has no trouble connecting to my laptop to access files, but the problem occurs when i try to do it the other way around. i get the error message, incorrect login, when i try to connect. is there an alternative method to fix this problem? thanks in advance.

Hi Duce,
Have you set a password for the useraccount your trying to login with?
Check if the user name on the vista is different from the one on the other system.
Normal practice is to create the same user name on both the machines. This somehow doesn't work well with vista. so go ahead and create a different username with a different password on the vista, than the other machine.
