A frequent problem always pops up in my workplace, sometimes computers fails to connect to the server or each other through their names, they only connects using the IP.
I am somewhat new to server environments. Having one with Windows 2008 R2 serving over 30 computers. Based on an advise from a friend, DHCP settings of the router, DNS servers are set to: 192.168.1.1 (Router's IP) as primary, and 192.168.1.2 (Server's IP) as secondary. Simultaneously, they fail to connect to certain websites including gmail, using google chrome it gives the error DNS_PROBE_FINISHED_NXDOMAIN.
The only way I figured out to solve this is through restarting the local DNS Client services.
Using DNS setting obtained from our ISP did not solve the problem, only caused other problems, requiring users to re-enter their AD usernames and passwords to connect.
Is this a dns problem? Or a problem in some other settings that conflict with the dns clients? I have little information about DNS server, and when I checked it out on the web, I found it hard to understand the use of this technology in small business like ours. I hope that someone here could enlighten me.

NXDOMAINfor popular websites is unusual. This means that your DNS server successfully received a response from an upstream source stating that the record did not exist, and not due to a communication problem.You need to examine your workplace infrastructure carefully and identify whether or not you have authoritative DNS servers (including DCs) that are configured to "steal" domains for popular websites. It's possible that there are leftovers of a misguided attempt to intercept specific DNS records to prevent employees from accessing them. Any network/security appliances which intercept DNS queries are also suspect.
As an example, what you're describing could occur if one of your servers is configured with a gmail.com domain, but not the others.
