Windows 2003

We recently moved office and we changed our ISP. The DNS forwarders were changed to 4.2.2.2 and we the dns resolution to be very slow and sometimes times out. the internal server dns is 192.168.1.1. The dns forwarders take a long time to resolve.

On a different subnet where we use 4.2.2.2 as the dns, no problems.

Is my internal dns corrupt? How do I resolve this issue.

are you running DNS off of a regular router or are you using Windows Server and have it forwarding outside requests?  From the IP address you have given it sounds like you are using a normal Linksys router.

Try switching the DNS forwarder to 8.8.8.8 and see if it changes.

at first, just simply PING 4.4.2.2 and 8.8.8.8 from the router to see the difference.
