Activate and disable the DNS-cache with a bat-file

[hackerman1]

Hi !

I´m using a HOSTS-file from http://winhelp2002.mvps.org/hosts.htm
Following their recommendations i have disabled the DNS-cache in order to prevent DNS-cache poisoning.

A few days ago when i was checking some settings in “Services” i noticed that the DNS-cache was enabled !?
I tried to disable it, which was denied because: “other services depends on it”.
I found out that it was a process from CyberGhost VPN which i installed two months ago that needed the DNS-cache running.

Mystery solved.
But, I don´t want to have the DNS-cache active, except when needed by CyberGhost, so how do I solve that ?

Here is the solution: 2 bat-files, the first starts the CyberGhost-service & the DNS-cache,
the second stops them.

Start CyberGhost.bat

SC START Dnscache

SC START CGVPNCliService

START "CYBERGOST" "E:PROGRAM FILESCyberGhost 5CyberGhost.lnk"

Note: the 2nd line is to the service that CyberGhost uses.
the 3rd line is a shortcut to the “main” program (GUI) of CyberGhost,
so of course you will have to modify those 2 lines if you are using some other VPN-program,
by changing the service & path to the program you are using.

Stop CyberGhost.bat

SC STOP CGVPNCliService

SC STOP Dnscache

And you need to run those 2 bat-files elevated (as ADMIN).
If you set the CGVPNCliService to start automatically then you can run the start-file without elevation.
But if you have used the stop-file and then wants to run the start-file again,
then it needs elevation because CGVPNCliService needs ADMIN-privileges.

Put the bat-files in in your program-folder, create 2 shortcuts on your desktop.
Then on both shortcuts under Properties → Advanced, mark “Run as Administrator”.
