but when i open

Hi.

If the machines have the same user account name but different passwords, make the passwords the same.

Or you could do it another way too.

Create a brand new user name with a brand new password.

If both machines have same user name but different passwords, sharing will not work.

i have set both XP machines same user and pwd... Like

XP MACHINE 1 = Login Administrator Pwd = okok123
XP MACHINE 2 = Login Administrator pwd = okok123

it is working if i open xp machine on another XP Machine

But i open xpmachine on windows 7

it said same login failure...

Plz help me out
