How long does a Windows client caches DNS entries? When I execute ipconfig /displaydns, I do not see the entries for the internet domain, even though I am able to ping those domain names.

Hello, if i ping my domain name it is listed without any problem when using ipconfig /displaydns. AFAIK default is one day http://technet.microsoft.com/en-us/library/cc959517.aspx.
