We recently installed fiber linking our buildings enabling us to eliminate one ISP. We have three servers. One in the building with the ISP we are keeping (Verizon). Two servers are in the building with the ISP being eliminated (Comcast). I'm having issues with the workstations in the building formerly served by Comcast.<br />
<br />
I changed the DNS server addresses on the two formerly Comcast-connected servers. The servers access the Internet without issue. The workstations, however, have Internet access problems unless I manually input the DNS server addresses on the workstations.<br />
<br />
Prior to the ISP change, everything worked properly with the workstation TCP/IP properties set to automatically obtain an IP address and DNS. Now I must manually input the DNS server addresses for proper access.<br />
<br />
What am I missing here?

DNS Server Change

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.
