Also many times with these Linksys, Netgear, etc, routers, especially if the
ISP service they have is giving them an automatic IP address on the WAN
interface, takes on the ISP's DNS addresses. So when you implement DHCP on
some of these routers (not all of them but I know there are many that do)
they automatically use these external DNS addresses in the lease. I know the
ActionTecs do this by default and you can't change them. PITA they are. The
router manufacturers designed these low-end routers for mostly home/consumer
use and were not intended for an AD infrastructrure, but nontheless, they
are used. No big deal, the idea is to just disable DHCP on them and use
Windows. On top of that, the BIG reason not to use DHCP on a router is in
all the cases I've seen, their DHCP service does NOT support DHCP Option
081, which dictates DNS Dynamic Registration, which we all know is a
necessary funtion of AD.

Using Win2k3 AD ourdomain.local (all MS servers and clients), I have had to
disable this option, as the well-known tcpsvcs.exe memory leak was eating RAM
and disk.

My understanding is that all I have lost is the ability to join clients with
OS older than Windows 2000 to my domain.
Please tell me I'm not wrong on this!
