Clearing local Cached DNS entries

casatech asked
Last Modified: 2010-04-14

My previous network was a network which was completely senseless.  We changed the network with vlans to create segmentation.  My question is the following.
We used to have the Domain Controller in Windows 2000 and it kept all the records.  After the change I still see that the Domain Controller still responds to old ip addresses and names.

For Example:
ComputerA -  (old network config)
ComputerA - (new config)

Ip address doesn't belong to ComputerA.  It belongs to ComputerXX.  But if I do a ping -a it still resolves to the old dns name.  
How do I clear all the old DNS configurations and just keep the NEW ones???
