I believe you could work something out here using the location awareness with different firewall policies. But beside you can simply set different set of firewall rules for RDP traffic - set the traffic to access on same lan local machines on 3389 to allow, and to remote lan to block.

There are few ways for resolving that issue:

1) Block Remote Administration from NTP -

Default Firewall Rules - The Deny rules includes blocking IPv6, IPv6 over IPv4, local file sharing, and Remote Administration

2) Block certain users in Specific Group to access Remote Desktop to specific 1 single server by Following Steps provided below:

  • Confirm that Symantec Endpoint Protection is Installed with All features (Antivirus / Antispyware Protection, Proactive Threat Protection and Network Threat Protection) on Symantec Endpoint Protection Manager Server and on Client machine and the Machines have been Restarted after Installation.

  • Go to the Specific Group to which the Policy is to be applied.
  • Click on Policies TAB, Right click on the Firewall Policy and Click on "Non-Shared to copy."

  • Edit the Remote Administration Policy. In Service Column, Add  Block TCP 135,  Block TCP and UDP 3389. Set Local port to 3389. Kept Remote Port "Blank". Kept Direction to "Both"

  • Add IP Address OR MAC address of 1 client (Machine be Blocked) in the Host Column as Local.

  • Enable the Policy and Click on "OK"
