Hi!

¿How to connect a Vista PC with an XP portable PC wirelessly?
I think I have some how connected both PCs for I can see each PC on the
other's network places folder in the windows explorer, but I am not able to
open any shared folder nor add any files to them.
From the Vista PC, when I click on the XP PC in the network folder of
windows explorer, I get a little window asking me for a user name and
password. I thought it was the user name and password of that XP PC I wanted
to access to from Vista PC, but was not recognized as a valid logon name or
password.
Is there any trick to it?

Thank you for any help on this
Cordially yours
