Please check your Server’s Hostname. Try, “DESKTOP-EM-SIMS-NLO” or the IP address of the ‘server’, “DESKTOP-EM-SIMS-NLO”.
Make sure that the client machines are on the same local network as the 'server', “DESKTOP-EM-SIMS-NLO”. And you are not trying to access the server from a machine on a different network/location via the Internet.
