I have a small network of 20 computers and 3 servers. I current have a Sonicwall firewall that does the DHCP for me. The question I have is the following.
On the DHCP settings should I have the local DNS server as the DNS server or should I use another one?
Current I use the local DNS server, but sometimes when I reboot one of the servers the other computers become very slow on the internet, and when the server is back up it all goes back to normal.
I have a domain controller that windows 2003 server, a secondary DNS server that is windows 2008 R2.
