Question : DNS mess duplicate entries with different IP

Have a customer with two sites with one DC/DNS server on each site.

Laptop pc's are switching sites on a daily basis. There are lots of duplicate entries where a pc have two or three different ip adresses on the same site. And some ip adresses are listed with two or three different PC-names.

How do I clean up this mess?

I know you guys need more information from me. Just ask for it.

Answer : DNS mess duplicate entries with different IP

You need to enable aging and scavenginig of DNS and set the non-reresh and refresh periods to low values - (1 day?). If you are using DHCP you also should reduce the lease period to the same value.
