Constantly recetada tincture DNS in Windows 7

Good time of day.
On the employee's computer with Windows 7 constantly recetada tincture DNS: did not like changed, anyway after the next login everything is back to the previous state.
The problem is that the reset all default configuration, and the DNS servers of the former provider. Therefore it is necessary to put all manually after each login.

It looks like this:

The interface is in Spanish, but I think the point is clear.

Microsoft offers to make a reset TCP/IP stack, that didn't help.
Tell me, please, what else can be the solution to this problem.
Thanks in advance for your answers.

Surely somewhere has registered the software from that of the previous provider.
1. There is a very useful utility from Sysinternals, called autoruns. It is possible to reach everything that starts automatically (looks different branch of the registry, shortcuts in the startup, and a bunch of different places), and gently disconnect:
2. If this does not work, you can run Process Monitor with special keys to catch all activity when you boot the computer and login.
3. In the most extreme case if the reptile to catch failed to write .bat file with something like 'netsh interface ip set dns "Local Area Connection" static 'and put in startup. Ideologically wrong, but will save you from manual work.
now I will try, thank you - heber_Herman commented on October 8th 19 at 03:09

1) check all scripts that run when you start OS and login
2) to test group policy computer

Can telepathically to suspect that it's the laptop Sony Vaio, comes with software to create profiles of compounds with different settings. Most likely written DNS in the profile and it is set as global.
how did you know?! :)
Yes, it really is a Sony Vaio :)
thank you, will look at the profile tomorrow - heber_Herman commented on October 8th 19 at 03:13
