Vista computers can't access internet through Firebox X15

Have a Firebox X15 router and for months now, every MS Vista computer that comes through our lab (as well as those we use internally) will not get internet access from the Firebox. The machines get valid IP addresses, but cannot resolve webpages until we manually set the DNS on these machines (i set the DNS to the ISP DNS servers). Has anyone run into this issue with a Firebox?

First of all, go to a command prompt again and type in nslookup.  Post what that says.

Then try this.  Go into your firewall interface and Change DHCP to give out a public DNS instead of 10.0.10.1
Here are Time Warner's DNS servers
ns1.biz.rr.com
ns2.biz.rr.com
dns4.rr.com

That should fix your issue.

Have you tried turning off IP Version 6 in your network adapter properties?
I've seen this cause issues before.

Excellent. I missed that the DNS was hard coded in the router settings. Removed it and all is well. I wonder why Vista doesn't like that while XP doesn't care. Thanks again.
