Sometimes when trying to start ArcGIS for Desktop on a slow network, the connection to the license server will time-out and the program will not start. To mitigate this you can add the license server’s port number to the license server name in ArcGIS Administrator.

  • Start ArcGIS Administrator

  • Click the Desktop folder and the Change… button.

  • Add the port number 27272@ to the server address.

  • Click OK twice.
