I have two Windows 2003 servers.  One is the primary DC, DNS, and WINS server.  The other a backup DC, DNS, and WINS, and Exchange/File server.  Both have DHCP running (with different address ranges) so that a server reboot will not cause DHCP issues.

We do a lot of our support in-house, but farm out more complex things.  This configuration was set up an IT service company I no longer use.  One of the reasons I changed is that they did oddball things that I now know to be incorrect (like changing the http: port to create a "secure" http: server).

The more conservative IT Support company I now use once commented that the router should be the DHCP server.  Whenever I call for support and they are gathering basic information, the support people always assume that the router is the DHCP server.  Some are quite surprised that the Server 2003 machine is the DHCP server.

I am only serving requests on the local 192.168... subnet.  All we are providing is an address, WINS server, and DNS server.  Several addresses are fixed by MAC addresses.

Is a router preferred as a DHCP server?  Clearly the current system works, but I don't know if the is any interaction between DHCP and WINS, DNS, or AD that could cause issues.

Thank you,
