Finding RDP machine after router flushed MAC IP table

They flushed the router tables again... where is my RDP machine.... Zenmap/nmap to the rescue... the only thing you need to know is the actual assigned windows name for your computer... and make sure your have it powered up... waiting for logon.. The nmap command would be something like this for scanning the 0-255 ip addresses on a 10.77.114.x

$ nmap -v -sn 10.77.114.1-255 -p 3389

Failed to resolve given hostname/IP: sn.  Note that you can't use '/mask' AND '1-4,7,100-' style IP ranges. If the machine only has an IPv6 address, add the Nmap -6 flag to scan that.
