This question is for PromiseNasDude.... It appears I've gotten an update of some kind via microsoft and now both Nas4300n devices will not allow me to map drives to them on any 64-bit machine ie(windows vista & windows 7)... Everything works fine on windows xp and 32-bit vista... I know the ports have changed and I followed the knowledge base article about changing the dynamic ports to now avail....I have the ports set just like my working machines... still no go...and ideas what's going on.
