Name cache not updating itself

I have a number of domain names registered with
dyndns.com. When the IP address of a host changes,
the dyndns name server registeres that change and
returns the new IP address within a few minutes.

I now find that my PC clings to the old address. Sometimes
it can take many hours until it updates its cache with the
new address. How can I empty the cache and force a reload?
I thought that nbtstat -R would do it but it makes no difference.

Second question: is there an easy way to view the cache?
