Hi sonic,
Assume you have installed Network Explorer on the Vista Home Premium with the nrserver and registered (log on), e.g. in the computer list, you can see your vista home premium.
Vista Home Premium does not enable the term server so that you cannot remote access to it using RDP. (Actually, Vista Home Premium has full term server package, just disabled. Google it, you will see how to enable it
)
If you won't like this, you may want to VNC. You can either setup vnc manually or use vnc add-on for NeoRouter downloaded from our add-on page. Then setup the Vista machine as a vnc server, so that you can remote access to it from another computer using the vnc client. When connecting, use the virtual IP address.
Check the Windows Firewall (icmp enable) and the Network Location on your Vista, see if the NeoRouter Connection is set to Private Network ( by default, NeoRouter will set it to private network automatically )
Thanks,
