@Rny: That’s what we think it should be but we will think about it again, thank you
@Vitor: if you choose default dns, Program will use modem/router dns ips and will Protect them
Hi,
The DNS-LOCK service can be easily bypass by terminating it in task bar or service manager.
Hope, it can be fixed. Thank you.
Hi,
Thanks for the useful and free software.
I would like to ask a question:
Choosing “Default” in the “combo-boxes” will make any protection? Or is it necessary to choose the other options, filling some numbers into it?
Thanks in advance.
Added , Please download new version.
can you please add silent command code
like “” DNS-Lock.exe 77.88.8.8:77.88.8.1 “”
On Win 10 v 1607 Anniversary Update (64-bit), after extracting & running DNS-Lock.exe on a Administrator Privilege, after selecting OpenDNS on both Ipv4/6, after clicking “Install Service”, it says “Service could not be Installed”, Please help………
Just use uninstall button
I’ve tried uninstalling DNS Lock but it keeps changing the DNS addresses back to a previous (not even a current) pair of addresses. How can I fully remove it?
Fixed Please try new version
No, the CPU problem is still not fixed for me on Windows 8.1 x64. 03-05% is not so high consumption but the funny thing is that even Comodo FIrewall and 360 Total Security use 0% CPU on my system…
EDIT: in v1.2 we have reduced the cpu usage to “0”
good
cpu usage proplem…………
Which Windows version do you use ? here is Windows 10 x64 1607 cpu usage of the Dns Lock
Web Link …
Nice idea but the service is CPU consuming (03%-05%).
Can you make it to use 0% CPU?
Thanks!
Thanks for the BUG report we will fix it
Interesting concept. Please fix “wiht”.
