I have a server running windows 2003 which is set up as a domain controller. It's domain is sandpit.com and I find that when I perform an NSlookup for an external domain name like Cisco.com that it will initially time out but subsequent attempts work ok. Also I find that the DNS resolution on connected clients takes a long time.
My primary DNS resides at Zoneedit.com. I have set up the dns on the server to be a stub for sandpit.com. I am pretty sure the problem is related to the DNS setup because I am not very experienced with DNS.
I have included a screen dump of the DNSmgmt screen.
Please help me resolve this.
