Bad cache?

I was having a little trouble receiving mail from a company here in
Minneapolis. We moved to a new ISP a few months ago & I suspected that this
companies DNS server had bad info. I called them up & asked the network guy
to try pinging our domain name from his workstation. Sure enough, he
received an IP address from our old ISP back.

So I have seen now that a DNS servers cache can contain out of date info.

How do you check a DNS servers cache?

How do you clean out old info?
