Newbie Question about DHCP and DNS

[Matt]

Hello,

I work with someone who has a DHCP service and a DNS service running on
the same server. Recently they had to reset their router and they did
not turn DHCP off on the router. After I changed this, it looks like
DHCP is not updating their local network, like a local computer has an
incorrect IP address in DNS, but it is correct in DHCP. I was just
wondering if anyone has seen this and what I could do to correct this
issue.

Thanks for all of your time.
Matt

First, turn off DHCP on the router. Then do an ipconfig/release followed by
an ipconfig /renew on all workstations that have incorrect settings or that
are not registered in DNS. The assumption here is that the DHCP server is
configured to update DNS which of course the router's DHCP server will not.
Also, expect IP address conflicts if the scopes overlap.
