We have a network server setup for our ArcGIS 10.5. I had them install the software on my machine. When I go to License Manager to check out licenses, there is an error response ("Not_Set" is an invalid hostname. Please enter a valid hostname.) When I go to the Admin Wizard, the option to Define a License Manager under the Browse button does not list our network. Suggestions?
The machine where ArcGIS 10.5 must have access to the server hosting the license manager. Make sure your machine is connected to the network. Instead of browsing the network, type in the hostname of the server where the license manager was installed. If it does not accept it, ping it using the command line. If you don't get a response, either your machine is not connected to the network or the license manager server is not reachable. Let me know what happen.
