Automated Way to Update DNS in SBS 2008?

This started as a question on how to turn off a warning in SBS 2008's logs regarding turning off DHCP warnings (Found here).

In short, turning off DHCP completely broke the server - several Automatic services, including AD, didn't start with the machine, which meant no one could connect to the domain. I manually started them, and the machine is now limping along.

But there are now loads of errors in the logs, mostly related to Exchange:

Process MSEXCHANGEADTOPOLOGY (PID=2380). The site monitor API was unable to verify the site name for this Exchange computer - Call=DsctxGetContext Error code=8007077f. Make sure that Exchange server is correctly registered on the DNS server.

I also get the following error with DCDiag.exe:
"The host could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc."

Digging around in DNS, there are a couple of issues. I see it only listening on (what I think is) an IPv6 IP - we're using IPv4, but that IP isn't checked. I can switch to "listen on all IPs" but I'm gunshy after the explosion with DHCP.

There are also several A records for an IP on a completely different subnet (10.x.x), but no references for the actual IP of the server (192.168.1.2).

So I think the issue is with DNS needing to be updated: somehow turning off DHCP caused a cascade of DNS-related errors.

So am I on the right track? If so, is there an automated way to update DNS, and get it listening on / reflecting the correct IP? I can manually change the IPs in the DNS forwards, but the reverses are doing my head in - and I'd rather not make manual changes if possible.

ipconfig is as follows:
