[Skunkworks] Windows Map Network Drive

Hello skunks and skunkettes.... I have a query, why is it that I can mount a hard disk of a node (192.168.* 177*.157) to another node (192.168.*177*.131) and both running on on Windows 7 P easily yet none of those can map to another node of a different subnet, that is, 192.168.*178*.34 or vice versa. Is there a way I *can map network driv*e within separate subnets bila a tussle of any sort? -- --Cursed be the day I was born if I do not learn a new thing today--*Chinese Saying* Regards, Adams John Opiyo.
