Remote session from client name a exceeded the maximum allowed failed logon attempts. The session was forcibly terminated. EventID 1012. this is on a DNS server on the public side - how can I isolate this problem ?

    It sounds like someone outside your network is trying to remote in to your DNS server.  One way to quell this would be to lock down the RDP ports at your firewall.

    the server is not behind a firewall.. will changing the default 3389 to something else help ?

    Not behind *any* firewall?  Not even a software one?

    Changing the port number might help, but a real hacker will just port scan until he finds something open.  If you have to have RDP, that's better than nothing.  Otherwise, I'd turn off everything you didn't absolutely need.
