I read and followed the directions in this thread... "How to make Windows 7 work with older Windows versions for networking and file sharing." I created 3 shares on my Win7 box and would like to access them, from my XP box, using UserName/Password authentication I tried these... directly connecting to \\<win7 box name>\<share> directly connecting to \\<win7 box name>\ Mapping a drive in Explorer ... in all cases I'm prompted for UserName/Password but it will not accept anything I type in. There are 2 admin users on the Win7 box and have tried both to connect to the shares. ... one of the admins is actually the same user/pw I have on the XP box and it still does not work. How can I get this to work?
