Windows 2003 DHCP DDNS Settings - - Not working
My DHCP server for my company resides on a Windows 2003 server. I have all XP clients and I'm using AD intergrated zone and have noticed problems where my clients DNS records are not getting updated corrently after the workstation gets a new ip address. If it better to let the client update DNS directlory or have the DHCP server do this. Please see my current DHCP settings below...

Is your server set to allow only authenticated machine updates? If this is set to allow only authenticated updates, and the machines are not in a domain environment, this may prevent ddns updates from your workstations.

What server do I check this settings on and where would I find it.
ASKER
I just checked my DNS server and its set to NonSecure & Secure updates...
Do you have an other suggestions. Are my DHCP settings for DNS correct that I listed above?

The Microsoft article 816592.. Here is a question right now my DHCP server is set to dynamically update client DNS information (Please see the attached screen shot above) but all of my clients are still configured to dynamically update there DNS information as well could this be part of my problem???

Should All of my clients are 2000 & XP based. SHould I enable the GP under \admin templates\Network\\DNS Client\Dynamic Updates to Enabled???

Yes
Yes

Do you think that the fact my DHCP server is set to register DNS records for client and the clients are set for this as well is causing problems????????/
No, what other settings do you have configured under under \admin templates\Network\\DNS Client\ ?
ASKER
NOthing !!!!!!!!!!!!!!!!!!
You might want to at least configure Dns servers :-) and update security level(mine is at Unsecure followed by secure - if this option is chosen, computers send secure dynamic updates only when nonsecure dynamic updates are refused.)

By default does 2000 / XP try to send secure updates? Also on my DHCP server should I leave the settings to update client A & PTR records for clients selected?

Here is a thought that I need some input on...Are my DNS settings correct???
Right now the following settings are setup on my Windows 2000 DNS server & Windows 2003 DHCP server
scavaging = 14 days (set to automatic) (Running WIndows 2000)
DHCP Lease = 7 days
Are these settings correct..
Should I create a GP that will set the TTL value on the client A & PTR records to a shorter time period??? Please adivse??

I have scavenging disabled, dhcp lease on 8 days, and TTL not configured
ASKER
Should let me make sure I'm understand everything correct I should do the following..
1) On my DHCP leave the setting for the DHCP to update client A & PTR records for legancy clients
2) What should I make my DHCP leave 8 days vs. 7 days
3) I thought scaving had to be enabled?
4) Should I specify in a GP under DNC-CLient the refresh interval at all???

ONly reaason I mention about the DNS client refresh setting is becuase I have client at remote sites that sometime have issues processing GP's correcntly becuase of DNS. I did not if increaseing the refresh interval would help this or not.
this setting will help with gp processing

I suggest that you create a reverse lookup zone as the first thread in the link suggests:

The setting to "Always wait for the network at computer startup and logon" is already enabled..
