DNS Windows Server 2012

[ShivP]

Hi all

At my dads workplace we are using BT business with an Asus DSL AC52U thingy
Internet download/upload speeds are good according to speedtest 70/20

However internet page loading is taking the **** a bit as it is very slow

In order to change the DNS for the computers on the domain do I need to simply change the one on the server and the clients will update automatically? If so how do I do this?

Thanks

It's a small business only 5 clients, it's just an i5 rig/16GB RAM with a few HDDs in there and running Windows server 2012 R2
