Assuming you already know all this but sometimes it just helps to start from
ground zero and go through the data flow to see where things stop working.
Ping -a uses the reverse lookup zones. Do they exist for the failing subnet?
Assuming yes, are they properly updated?

So to narrow it down, I can ping -a my subnet, and resolve name, however I
can't resolve other subnets I assume its my DNS server settings then.

For some reason ping -a does not resolve any DNS name anymore, it used to work,
tried it on 2 PC's and 2 Servers.
Google is no help, any ideas?
