Nav 2017 client access help

Dear Friends,

Please help me as I am unable to give user access to a desktop for nav 2017


1. Nav 2017 is installed in Server and in the server system I can access both web client and windows client.
2. If we want access the Nav 2017 from different desktop in the network, the
error is coming. I can ping server from desktop.
3. I have also copied ClientUserSettings file in user folder also in related folder in programdata folder.

Please suggest.

Warm regards
Kris
