Hmmmm, something is up with DNS at work. Randomly (anything from a week to 2 months) it seems to stop resolving .co.uk for some domains (especially www.bbc.co.uk) ? Nothing recorded in the eventlog for the times while it is behaving like this. Restarting DNS server fixes the problem for a while until it breaks again.
I recently patched server 2008 to SP2 as I found some issues that were fixed in that SP (like incomplete zone transfers which broke some stuff a while back).
But the service pack does not seem to have fixed this random sulking occuring in DNS.
For now I have enabled DNS debugging to a file on the system and restarted DNS, now I will need to patiently wait for it to act up again so I can have a peek and see if anything looks amiss.
I can find nothing solid on google either. If I ever get to the bottom of it I’ll re-post here, but in the mean time if anyone has any ideas let me know as I am stumped.
