We have recently upgraded to Windows Server 2008 R2 and now, at random
intervals DNS stops working. After lots of trawling the web, it appears that the
problem is experienced by almost everyone – and is caused by Microsoft’s “E”
DNS. The only way to get DNS working again is then to re-start the DNS service –
something that is a complete pain, not to mention time-consuming!

Thankfully we have found a simple fix:

Open command prompt

Type: dnscmd /config /EnableEDNSProbes 0

press Enter.
