Also note this:
DHCP does NOT update WINS (only the
clients do that.)
DHCP server must have the scope configured
with the DNS zone name (otherwise how would
it know which zone to register in), the DHCP
server must be able to FIND the "master" (usually
the Primary or equivalent DNS server for that
zone.)
DNS server must be set to dynamic for the zone.
If set to Secure Only the DHCP server must be
IN the DOMAIN and must be authentication.
Check you DNS in general:
--
DNS for AD
1) Dynamic for the zone supporting AD
2) All internal DNS clients NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2
4) If you have more than one Domain, every DNS server must
be able to resolve ALL domains (either directly or indirectly)
netdiag /fix
....or maybe:
dcdiag /fix
(Win2003 can do this from Support tools):
nltest /dsregdns /server
C-ServerNameGoesHere
http://support.microsoft.com/kb/q260371/
Ensure that DNS zones/domains are fully replicated to all DNS
servers for that (internal) zone/domain.
Also useful may be running DCDiag on each DC, sending the
output to a text file, and searching for FAIL, ERROR, WARN.
Single Label domain zone names are a problem Google:
