But if for whatever reason a device connected to AD doesn&amp;#x27;t use the AD server as its DNS server, for example if it&amp;#x27;s a laptop and not connected to the corporate network, then you&amp;#x27;ll be offered a _different_ search domain like `myisp.com`.  Which probably _won&amp;#x27;t_ resolve `corp.myisp.com`.  So the built-in resolver will after all walk its way up the search domain and check `corp.com` QED.</text><parent_chain><item><author>LeonM</author><text>For those not familiar with the corp.com situation:&lt;p&gt;Corp.com was (is?) the default example domain in many applications from Microsoft.
