This value disables that automatic cache updated from the DNS root servers. Useful when there is a problem with the root servers, or if you wish to completely control DNS updates.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value, named "AutoCacheUpdate" and set it to "0" to disable automatic updates.

Restart Windows for the change to take effect.


(Default)	REG_SZ	(value not set)
AutoCacheUpdate	REG_DWORD	0x00000000 (0)


	HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

Settings:

System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters]
Name: AutoCacheUpdate
Type: REG_DWORD (DWORD Value)
Value: (0 = disabled)
