DNS Lock

In the eventuality that you are constantly having a hard time maintaining a stable connection to the Internet and receive errors related to the DNS server, then the most likely cause is that your DNS settings are changing due to various reasons, including malware attacks.
DNS Lock is a tiny utility designed to help you address this issue by proving you with a straightforward method to install your favorite IPv4 DNS server and protect it from being modified.

Comes with a minimalistic, yet user-friendly interface

The application does not require setup and since it is portable, you can decompress it in any desired location on your hard disk. The program comes with a simplistic UI that consists of a small window featuring its two primary functions, namely install and uninstall service.
While it is true that the window could have been slightly larger, it is intuitive and unlike to give you any challenges, regardless of your experience. Moreover, the app provides you with clear instructions on how to use the tool, an option that can be helpful for users who did not work with similar utilities before.

You can install a custom or a standard DNS server address

As indicated in the interface, the functionality of the utility can be summed to specifying the IPv4 address and then hitting the Install Service button. You will be happy to learn that you can install several servers, as long as you add them separated with a comma. Uninstalling the service is a quick matter of selecting the server you no longer need.
It is worth mentioning that the program provides a few options for standard DNS servers that you are likely to use. Then again, you can add your own server, providing you know the address, as the utility does not have any limitations in this sense.

A useful tool for fixing DNS servers-related Internet problems

If you grew tired of disconnecting while playing, watching videos or browsing the world wide web due to the fact that the DNS servers are not responding, perhaps DNS Lock could help you correct this issue.
