Cannot connect win xp or boxee box to a private share

No trouble finding public share, when attempting to map to private share win asks for user name and password. when the correct one is entered the same user name password box comes up again and again, any suggestions?

Hi there, Windows has some issues when you try to have public and private shares at once.

What if you disconnect the public shares, map the private ones and give the credentials and then map the public shares again?
