Using this laptop, I can log into the router and see both it and the problem PC in the list of connected devices, each with the dynamically assigned IP addresses as seen using ipconfig on each.Unplugging the ethernet cable shows the connection status changing in the list of connected devices in the router.

I can do it manually by going through the "Properties" in each client, unchecking and re-checking "Update associated pointer (PTR) record" and clicking ok in the "Forward Lookup Zones" for our domain.

That gets them to generate a PTR in the "Reverse Lookup Zones" in the appropriate scope, however, once they change IP addresses, they do not update unless I go through the process again.

As you could guess, that is quite tedious and annoying.

As far as my other settings go, in the IPv4 "Properties" under DHCP Server, I have gone to the DNS tab and made sure that "Enable DNS dynamic updates according to the settings below:", "Always dynamically update DNS A and PTR records", "Discard A and PTR records when lease is deleted", and "Dynamically update DNS A and PTR records for DHCP clients that do not request updates..." are all selected.

ddns-updates on; ddns-update-style standard; update-conflict-detection false; allow client-updates; ddns-domainname "local.domain.com"; ddns-rev-domainname ""; update-static-leases true; default-lease-time 7200; max-lease-time 7200; authoritative; [...] Whenever a client gets a new IP from the DHCP, the DNS registration works perfectly.

However, these "dynamic" DNS records expire after some time (a few weeks)...

Using Netflow, I could see the ip address of the offender but couldnt see the hostname of the computer/workstation that was the offender.

Here is my config for DHCP on the switch -ip dhcp pool PC network 10.1.70.0 255.255.255.0 domain-name dns-server 10.1.1.1 10.1.1.2 default-router 10.1.70.1 lease 8This is an office across the street from the main building.

I also tried static settings in the available range and tried using open DNS IP addresses.

They also have a laptop which connects to the same router wirelessly using DHCP and it is working fine.

How can the DHCP be configured to refresh the DNS records after a given time interval?
