Control the list of domains to search when performing DNS lookups.
To use this policy, click Enabled, then click Add, type a domain name, then click OK to add the domain to the list of domains to search. Add as many domains as you want in this manner. When you are finished adding the domains to search, click OK to close the dialog box.
At any time while the policy is enabled, you can select a domain in the list and click Edit to change the name, or Remove to remove it as a domain to be searched.
This policy can take effect dynamically at the next group policy refresh interval without rebooting the computer.
