Just as I said. Indy or Sandeep. And, I mentioned TS. I think, as well, it is the best way to go. But, if you don't have Indy or Sandeep (or others on here to be fair), you need to get a good IT tech to set it up.
The key to a good network is setting it up correctly the first time. DNS and DHCP, especially DNS is key for all these things to work. The guy I work with who has done this for 35 years and works for Microsoft told me that when he went to college (yes, they had computer science back then), he was told by one instructor that when something went wrong on the network, it is DNS, DNS, DNS. At least first.
Agree Indy?
