I think Bob needs to reconsider how he is going to consolidate his servers at home, he needs a physical DC. The DC should also run DHCP, DNS and WINS and probably NAP if Bob is planning on using that technology, of course it should run Server Core.
Why?
So he can use
- user accounts from AD for his service-accounts, a physical DC is faster to load than a virtual one in case of total loss of power.
- use DHCP to provide and secure IP-adresses for the machines (the servers IP-adresses should be reserved on the DHCP-server and setup manually locally on the servers). DHCP should be allowed to make and own DNS-records on behalf of the machines so a rogue machine on the network won't be able to spoof anything in the infrastructure and you can allow DHCP and DNS to make automatic cleanup.
- WINS is still nessesary because some products still try to do NetBIOS name resolution first and DNS second and it's annoying to wait for the timeout to happen.
By the way: The red Q on the shipping award behind Bob, what product is this for?
Does Bob use a Home Server?
