The first thing I would do is telnet on port 3389 and make it sure the port is reachable.That would be telnet serverip 3389. In order to perform telnet make it sure that your server and client are pinging and reaching each other and I would also like you to see if the remote desktop is enabled on the server and firewall/AV is turned off, regarding the network browsing please start the computer browser service on the Windows 2008 r2 server.http://www.arabitpro.com
