Internet requests started getting painfully slow, so I looked more into. Turns out it’s DNS resolution that’s being very unpredictable. I have the DCs forwarders set to our ISP DNS. If I go to the DC and do an “nslookup”, I can’t get anything to resolve. If I set my client DNS to something public (188.8.131.52), everything is totally fine, so it’s definitely DNS the problem. What else can I look for? I can’t resolve names on the DC, so no way the client passing requests to the DC will get DNS back. It’s not all the time, but probably 8-9 sec for a resolution. any ideas?
