Update HelpServer Name in "ClientUserSettings" for all users

Dear All

I installed Help Server in a separate server, but in every users's local "ClientUserSetting", the "Help Server" is the Client server itself (Default value?), I can change the setting in "ClientUserSettings", problem is we have several hundreds users and how to make sure the new user will have the correct "HelpServer" in their "ClientUserSetting"?

Will re-install RTC client help?

By the way, version is NAV 2016.
