Re: DHCP address leases

Tech-Archive recommends: Fix windows errors by optimizing your registry

If the server has a static IP it would not obtain addresses from another
server, but I have seen two dhcp servers with the same scopes of adddresses
cause problems on the network. I have never heard of a static entry
becomming dynamic.

Also, regarding the address the server has, you need to make sure the scope
does NOT include the server's static IP address, or that that IP address has
been excluded from the scope.
