I'm having an issue with DNS lookup requests timing out on our network. Only DNS requests for names outside our local domain are experiencing issues. Nslookup requests locally on the DNS server itself also demonstrate the issue, which would suggest the problem is with the DNS server itself and not the network between the users and the server. Not every request is timing out, but it's happening frequently enough that internet usage is painful for everyone in the office. I've been beating my head against the wall trying to figure out what the cause might be, and in spite of a few moments of false hope have struck out so far. Any suggestions on what I should be looking at would be greatly appreciated.
I didn't find the right solution from the internet.
