That usually means that there is no PTR record for the dns server itself. &nbsp;It doesn't necessarily mean that the DNS server is unavailable. &nbsp;The PTR record is what would resolve 10.10.10.4 to a hostname. &nbsp;If your name resolution seems to be working, then you may just want to add a PTR record for 10.10.10.4

Is Reverse DNS configured? <br />
Check under Administrative Tools &gt;&nbsp;DNS and see if there is a Reverse Look-up zone configured if not, that is what is causing that error.

You DNS servers are unavailable or it cannot contact them. Are you connected to a wireless network? sometimes i have been connected to multiple networks and it tries to puch traffic down the wrong connection.<br />

Hope this helps.<br />

2003 AD domain<br />
When I try to do a nslookup to any ip or fqdn, I get the following:<br />
**cant find server name for address 10.10.10.4: non existant-domain<br />
default severs are not available<br />
<br />
Probably another stupid question but why is this?

Nslookup question

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
