We have Verizon fios 25/25 line
When I am using external dns 184.108.40.206, our internet is as fast as what it should be and what we pay for. There is no lag, everything works as smooth as I have ever had the pleasure of working with any network
We have a small domain from within the network which is based off of a Single DC and an Exchange server
the DC is also the DNS server which in turn handles all of our AD
When ever I use the DC/DNS server as the server on our clients..
There is a 2 - 3 second lag before it resolves.. this gives our internet experience horrible issues especially when loading sites which pulls date from multiple domains.
when ever i use external dns, it works instantly
Can someone help me trouble shit this, i honestly dont even know where to start. . thanks
