Problem in detecting MBWEII with win 7

Hi there, 

i’ve just buyed a new MBWEII and i’ve connected it to the lan and all the stuffs.

Mac Leopard does recognize it without any problem, while my Win7 does not even see it on the net.

Can anyone help me please!? I’m getting crazy for this!

Thanks all

ok , problem solved, it was  conflict on the net.

thanks all anyway

Was it a permissions issue?
