UTM 9 updating DNS entries in Windows

Hello,

We currently have a Sophos UTM 9 that provides DHCP to our network. However we use a Windows 2008 DC to provide DNS to that same network. Recently we've been encountering many issues with duplicate DNS entries in the DNS manager. I've enabled scavenging and upped the DHCP lease to try and combat this but it still continues to happen. Is there a way to configure the UTM 9 to dynamically update the Windows Server's DNS entries whenever a client receives a new IP? I believe this would resolve the issue as currently we have several workstations that have anywhere from 2-4 entries in the DNS table.

Why do you use the UTM-DHCP instead of using the build in DCHP from 2008R2?

When you use MS-DHCP it will update the MS-DNS whenever a change occurs.

Unfortunately I didn't set this up, I'm new with this position and want to try to make the best of what's currently setup. I was under the assumption that some DHCP servers could update MS-DNS whenever new addresses were handed out?
