The problem is that the Windows RPC system service is blocked, by default, in the AVG Firewall configuration. You can allow this service in System services but it is not secure. It is suggested that you create a new system service which will allow incoming TCP communication to local port 4899. If you change the default Remote Administrator port, you will have to set a system rule for the correct port.

 

You can change AVG Firewall configuration this way:

  • Open the AVG program.
  • Choose the Firewall settings option from the Tools menu.
  • Select Profiles -> your default profile (e.g. Standalone computer) -> System services.
  • Click on the Add button.
  • Type a brief name of this new rule (e.g. Remote Administrator) and the System rule details switch to Allow for all.
  • Click on the Add button and then on the Add service button.
  • Fill in the Service item name column (e.g. Radmin) and click on the Add button.
  • Protocol - TCP, Direction - In.
  • Local ports - 4899 (or as specified in Remote Administrator application).
  • Remote ports - "*" (without quotes).
  • Click on the OK button.
  • Tick in the Radmin service in the list of Defined services.
  • Save the settings by clicking on the OK button.
