To purge the resolver cache on any Windows 2003/XP (DC or other) it's

ipconfig /flushdns

To flush the cache from the DNS server, it must be done through the GUI by right-clicking the server and selecting the appropriate option.

There is a client side and a server side DNS cache.  As stated above, to clear the cache on your server:

Right-click the server object in the DNS console and select "Clear Cache".

Ah well, I was hoping there was a command line to automate the server side one.
...At least now I won't waste my time lookng for something that isn't there.

I apologize!  I didn't see the 'command line' in your thread.  You can do this with dnscmd.exe.  See the syntax here:
