DNS records being taken from second interface

When a user comes in via VPN, his IP is registered in DNS.
However, DNS is also registering the home IP of the user.

How can we make sure that the home IP of the user should not be registered in the DNS?

DNS: Windows server 2008 R2 SP1
DHCP: Windows server 2008 R2 SP1

On the computer that is VPN'd to your network

Check the network properties on the Local Network adapter

Go to Advanced TCP/IP Settings select DNS tab

Is Register this address in DNS checked if so uncheck it

How is the MAC connected to the internet? wifi or by lan?

What ip address range is the mac on when not VPN'd in?

What ip address range is the VPN connection
AcklesAuthor Commented:
there are more than 200 MAC's, so can't say how they will be connected.

They can be in any range as we have no control once they are out...

VPN ranges vary as per the group membership, but this is not handled via DHCP, that is why I am asking if we can only update DNS for IP's being handed out by DHCP then we can isolate this problem...

Are they logging into the domain with a domain account?

I found this that may help you


I am thinking that the mac do not register into DNS

Do you have any third party app installed on the MAC?

Do these mac ever connect on the local lan? If they did maybe it registered in DNS the local nic mac address and is remembering that info

Just some thoughts

Yes they logged in domain with domain account. But the ip registered is not of LAN
