How do you have DNS configured? &nbsp;What do workstations and the server point to for DNS?<br />
The usual configuration is to have the server configured as a DNS server and have everyone point ONLY to it for DNS. &nbsp;You can set up forwarders on the server to whatever DNS servers your ISP recommends or leave them blank.

Help needed. We have a network 2012 server standard and feels like there is a network problem somewhere. All seems ok then something rears its head. Today we installed Sage 2016 and it uses the Sage data service which is flaky at best but we cant connect to it. Sage cant understand it but it brings to a head there is an underlying network protocol error somewhere. The server was migrated off another server and all seemed to go ok but there were old server DNS entries in the DNS server which were removed. Is there any way we can test all the protocols etc and DNS?

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
