DNS Name Server Caching

I am trying to figure out a few things about DNS Client caching. Specifically, I'd like to know how many name servers for a particular domain are cached when the client resolves a record for the first time, and what happens if the cached name server becomes unavailable when future requests are made. Also, is there a way to display the NameServers in a client cache on a windows servers. ipconfig/displaydns only seems to display the cached A and CNames, not the NameServers.
