Windows Work Group Username and Password help

[speedy1]

I have 2 laptops joint to a work group, windows 7 and windows xp.

I can see both of the laptops in the work group and can access my windows 7 files from the xp laptop after I have entered the username and password in the dialog box.

When I try to access files from the windows xp laptop, using windows 7 laptop a dialog box appears asking for username and password. Im not sure what I have to enter in here.

I have typed in the admin user name and admin password set on the xp laptop but this does not work, any help would be appreciated.

might sound silly but have you tried XPMACHINENAME\adminusername and password on the windows 7 laptop (replacing with appropriate values)

Could be the Windows 7 laptop is trying to login using it's machine username.

I've found this to be the case that if logging in using only a username without the machine name prefixed, Windows XP often assumes that the account used must be one the remote PC whereas Vista & 7 both assume that the account must be on the local PC, not the remote one.

Hopefully that made sense.
