Printer and File Shareing

I just installed W7 RC1 and now I cannot connect to my windows 2000 computer that has my printers. When I try to connect it comes up with "Logon failure: unknown user name or bad password" With W7 beta I was able to connect.

I noticed that when I click Use another account it has a domain listed under the username and password area and that domain shows up in the username like this Domain\Username.

No Fix for this?
