@asingh why not use teamviewer? just assign a static Local IP to the D/L rig.. The teamviewer's file sharing feature is also very useful.
i used to access my monitor-less PC through my Laptop using teamviewer and it was good. Laptop and PC were connected through a router.
But through remote desktop u can also connect the local drives to transfer data
@asingh u can set a same range static ip on both the pc's
I had created this tutorial long time ago .. have a look at it.
