DHCP Dynamic updates issue

Hi
my site: windows 2003 SP2 DC, DNS, DHCP
ip range: 192.168.1.1 - 192.168.1.250 / 255.255.255.0
ip exclusion : 192.168.1.1 to 192.168.1.25
my client machines are : windows XP SP3.

Suddenly i noticed the dns records are not updated in the dns server. the
dhcp server leased ip addresses to the clients. In DHCP the icons of the
computers have a pencil in it & it means " Active lease, DNS dynamic update
pending. This address is not available for lease by the DHCP server"

I am enabled "Always dynamically update DNS A and PTR records" in the DNS
tab of DHCP properties.
What does it mean? how to solve this?
Help me out.

Hi
-At first glance sounds that the account used by DHCP server is not working
correctly, check if the Password expired or if is using the correct account
or if you change it recently to a different account.

Hi Jorge
I am using Domain & enterprise admin credential accounts. But i am checked
the "Password never expires" option. Recently i am changed the password of
the account.
I noticed the eventvwr, the DHCP Server error log is created as "The DHCP
service failed to see a directory server for authorization."

Do the needful.

The account that I was talking about was the account used by the DHCP server
to register the DNS records, you can find it under DHCP server properties.

-Are you sure that the credentials are valid? Can the DHCP server get the
DC?
-Do a test, delete the DNS record for a given workstation, go to the
workstation and release the address, then renew it and try to register DNS
record.
On the workstation from cmd:
ipconfig /release
ipconfig /renew
ipconfig /registerdns

after this what errors do you see in workstation? And the DHCP server? Is
the record registered?

Forgot to mention that you shouldn't use a admin account for DHCP service, a
normal user account should do the job just fine. Another problem with
changing the DHCP account is the DNS record ownership, if you change the
account you may need to delete the previous DNS records registered by the
old account.

Hi
Site: Windows 2003 SP2 DC, DNS, DHCP
Client : Win XP SP2

i was configured dns server in the dc & afterward due to some reason i had
changed the DC name. (Like from skb.com to sk.com).So i promoted the DC & its
working fine with all components.
But i got repeated error in DNS server eventvwr as:
"The DNS server was unable to open zone _msdcs.SKB.COM in the Active
Directory from the application directory partition ForestDnsZones.SKB.COM.
This DNS server is configured to obtain and use information from the
directory for this zone and is unable to load the zone without it. Check that
the Active Directory is functioning properly and reload the zone. The event
data is the error code."
i am not using the skb.com dns server right now.

How can i solve? the Event ID is : 4007
