Shorten the built in Windows DNS cache time
To force Windows to keep positive entries in DNS Cache for only 4 hours instead of the default 24 hours we need to apply the following change to the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
DWORD: MaxCacheTtl
Value: 14400 NB - make sure you enter the 14400 (seconds) as Decimal Base and NOT Hexadecimal Base!
