I have a home network setup with a Vista machine, a NAS and a XP computer. The Vista PC is able to read and write to the NAS and can see the XP computer. The XP PC does have access to the internet but can only see the NAS as uPnP and cannot read or write to the NAS and does not see the Vista machine or the WORKGROUP for that matter. Both computers have McAffee protection and "trust" each other.What did I do wrong? Can anyone please help?1 person got this answerI do too
