configure policy to change the DNS address from manually to automatically

Hi all,

we have set the DNS server address of computers manually, now we want to change them to "Obtain DNS Server address Automatically"

but the number of computers are too much to set them back to automatically.

I want to know is there any way to change them by configuring policy in Active Directory

so by the policy all the settings will change at the same time

Any idea?

Best Regards,

Brilliant
