What is your platform? Is the client machine 32bit or 64bit? I am assuming you set the DNS up the exact same on the client machine.
If your platform is Windows and your machine is a 64bit, be sure to use the 32bit Datasource Admin tool ( C:\Windows\SysWOW64\odbcad32.exe ).
If my assumptions are incorrect, the platform and specs on the client machine will help others assist you.
Thanks... I’ll check on it.
