thanks stefano.
all the clients are on the same network and in the same workgroup, (even though i heard it was possible to use different workgroup name), i dont know much about the logs yet so i dont know what log to look into, i can confirm though i can use FTP, web... but cant connect to SMB, i dont know even though how to connect to it, i tried start --> run --> \\xxx.xxx.xxx.xxx but i get an error.
Yes, i confirm i have the same issue in vista and xp home. i am reading, that's all i've been doing lately, reading the docs.
