2008 a DNS oddity
Recently I have upgraded all bar one of my Windows servers to server 2008. This included upgrading a Windows 2003 Active Directory controller. It was a pleasant surprise to discover that everything went perfectly well with absolutely no initial issues. However after a couple of days one very odd issue began rearing its head.
My Windows 2008 DNS server (PDC upgraded from 2003) occasionally decided that it can no longer resolve .uk domains. It doesn’t matter if it is .co.uk, ac.uk or whatever .uk it just flat out refuses to resolve them unless I restart the service.
A second Windows 2008 server that I installed DNS on as a secondary server has the exact same issue. After a couple of days it will just stop resolving .uk domains!
After plenty of head scratching and searching I finally discovered this article on technet.
It requires a bit of registry editing but what puzzles me is that if the problem has been fairly well known for almost a year (that technet article is dates 29th January 2009) why is the fix still a registry hack?
the article at the top sugests that using DNS forwarding will solve the issue instead of using the reg hack… i have 2 DNS servers in house (an old 2003 box waiting to be upgraded to 2k8 and a 2k8 box). both are set to use the OpenDNS servers for DNS lookup… its very nice and fast.
Tiernan,
I was going to setup a forwarder but I figured I would rather find a solution. I’m a glutton for keeping as much as possible in house
