I have inherted a network which has 1 primary(Lets call it primo 1) and one secondary DNS server - we also have 1 primary dns server(Lets call it primo 2)that enables external communication since it has its root hints populated with external DNS servers.

The issue is that  primo 1 is a domain controller with dns functionality but it fails on recursive dns quries to external servers.I have had to populate its root hints with data from primo 2 (Which was querying recursively previously but now has the same issue as  primo 1).
Now users are complaining that internet connectivity drops out every now and then- I really rhink it is dns related as no other changes have been made.

Primo 1 is also a very old machine that takes 30 minutes just to reboot - I really want to transfer the primary dns to a faster machine.Primo 2 is up for reformatting so that rules it out for at least 2 weeks.

Any help will be greatly appreciated- I have dns forwarding activated and forwarding to the correct external ISP dns servers but it still does not work; hence my populating  dns servers root hints.
