more than one, make sure the most reliable ones are listed first.
Cause 2: The additional domain names entered in the TCP/IP control panel

Solution 2: Make sure you have entered valid domain names in the Additional
Search Domains box in the TCP/IP control panel. (The domain name area
only appears when the control panel is in Advanced mode.)
Cause 3: The domain names entered for an implicit search are incorrect.
Solution 3: If you have entered starting and ending domain names for an
implicit search, double-check the TCP/IP control panel to make sure they’re
correct. (The implicit search name area only appears when the control panel
is in Advanced mode.)
For complete TCP/IP setup instructions, see Mac OS Guide, available in the
Guide menu when the Finder is active. For help determining what values to
enter, contact your network administrator or Internet service provider.
