Domain Name Resolution (DNS) on Windows is done through a locked-down system with minimal configuration available.

Hosts
The hosts file (c:\windows\system32\drivers\etc\hosts) is a list of addresses and names, especially for local hosts and machines. A basic hosts file looks like:
127.0.0.1 localhost
Cache
Windows caches name lookups.
To clear the cache, try:
ipconfig /flushdns
