Server Publishing Rule in TMG 2010

Dear All,

I ma New for TMG 2010, Install TMG 2010 Std Edition (Edge Firewall), now i am trying to configure the Server Publishing Rule to access the Remote serves from anywhere its giving me the below Error:

Description: The server publishing rule Exchange Server Access, which maps Local IP:8989:TCP to Public IP:3389 for the protocol RDP (Terminal Services) Server, was unable to bind a socket for the server. The server publishing rule cannot be applied.
The failure is due to error: The requested address is not valid in its context.

Could you please check this and guide me how to solve this issue.

Thanks
Kumar

Normally means that you already have a rule or service on the TMG box that is using the required port number.
