Do you have a domain????  If so, then your workstation DNS should only point to that DNS server.  However, if you are taking it down a lot, you could make the server the first DNS server in the list with your 200 device the second one in the list.  If the first one is down, then the workstation should go out to #2.

For the best operation of the domain, the DNS server should point to itself only and the workstations should only point to the DNS server.  That way any network traffic hits your server for Resolution first.  If it is found in its cache, it returns the correct name resolution.  If it does not, then it will query the Internet Root servers for the resolution.  

I don't believe your 200 will pass on custom DNS to the workstations, but you will get so much more out of your DHCP server by using the one on your Windows Server only.  What I do at some remote sites with 1 server is to setup DHCP like you have, but leave the firewall DHCP disabled.  If I ever need it, I can just enable it.
