KB26451 - Frequently Asked Questions about the supportability of Terminal Services on MAC clients with PCS

This article provides information about the frequently asked questions about the supportability of Terminal Services on MAC clients with PCS.

Scenario:

Assume that the IP address of a target MAC client system is 10.130.35.147 and the Terminal Service profile is configured on the device:


 

The user clicks the Terminal services bookmark for the MAC system from a windows system ( that is, test-mac) to launch the terminal service session.  After clicking the above bookmark, the Terminal service is not launched and the following error message is generated:



When using the HOB applet for the Terminal service session, the following error message is generated:

• Does the Terminal Services, which are configured to a Windows system as the Target, work from a Windows source?
  
  Yes; this works as designed, as the terminal services on the PCS device is designed to abide by the Windows MSRDP protocol and uses the 3389 TCP port.

 

• Does the Terminal Services, which are configured to a Windows system as the Target, work from a MAC source?
  
  Yes; even this works as designed, as the target is a windows system and it is designed to abide by the Windows MSRDP protocol and uses the 3389 TCP port.

 

• Does the Terminal Services, which are configured to a Mac system as the Target, work from a Windows source?
  
  This does not work as designed, as the target is a non-Windows system and it is designed to abide by the Apple RDP protocol - Apple Remote Desktop  (ARD), which mainly works on the UDP protocol on the 3283 port and not on the 3389 TCP port.
