Dynamic Update Pending ???

[dave Admin]

My network is Server2003, SP1, all workstations XP, SP2 using Microsoft DHCP
and DNS. I have threee subnets in different locations and DNS servers at
each location. At one remote site almost half the worksstations listed in
the DHCP consile have an icon indicating "Active lease, DNS dynamic update
pending. This address is not available for lease by the DHCP server."

None of the workstations listed in the DHCP server in the main building have
this icon. What does this mean and is it something that needs to be
modified??

I'm going to make a stab at this. I think you may have site replication
issues. The DNS zone has been modified locally, but zone transfers may not
be up-to-date. Check the serial #s of the zones and see if they are in
agreement. How are your sites connected. One domain? An independent domain
at each site?

Kurt,

Thanks
I'm not much of a DNS guy. I have one domain, three sites, each on its own
subnet. AD replications work good, no errors with dcdiag. Apps such as DFS
work just as they are supposed to. I have a DNS server in each site, each
site has a DC.

Where do you locate the serial# of the zone???

Kurt,

The "HELP" stated the serial # of the SOA resource record is the same when
the DNS servers have the same version, different serial#'s indicate a need
to replicate differences. All three of my DNS servers have the identical
SOA serial# indicating that they are in sync. So now I am even more
confused.

OK, so zone transfers are not the problem. So this zone exists as AD
Integrated, running on DCs at each site? Just to be sure, the DHCP server is
running on a domain member server or DC? The DHCP server is pointed to AD
DNS server(s) as it's only DNS server(s)? Dynamic updates are allowed?
Anything in the DNS or Security logs about DNS updates failing? That about
exhausts anything else I can think of. There are others here with a good
deal more DNS experience than I have, hopefully some of them will weigh in.
Rebooted recently? (sorry, I have a keen eye for the obvious...)

The DHCP servers run on DCs at each site.
The DHCP servers point to the DNS servers as their only DNS servers. ( The
ISP's are setup under Forwarders)
No logs about DNS failures
The servers reboot after backups each night.

And the workstations are all setup the same for DHCP and DNS.

And one more, secure dynamic updates are allowed by the DNS servers. Wish I
cold think of more. Please post what fixed it when you get to the bottom of
it.

Have you assigned a user account with a non-expiring password in the DHCP
scope properties for the DHCP server to authenticate with the DNS server?
