Anything yet?
Expert:  Lorenz Vauck replied 7 months ago.

Dear Client,

I am sorry to hear about that problem. My name is***** and I am a tech expert with 19 years of experience.

Can you please let me know what exactly you mean by "DNA" settings? Do you mean that the computer has no internet connection at all? Even not if you are connecting it with an ethernet cable?

Please type in the box below, then click on the "Send" button to send me your reply.

Thanks for your patience and best regards,

Lorenz Vauck

Thank you. Please try to reset the TCP/IP stack by downloading this utility https://www.majorgeeks.com/index.php?ct=files&action=download& from a computer that has a working internet connection, put it to a USB stick and run it on the computer that has the issue with the network. Please let me know if it worked.

Customer: replied 7 months ago.
Will do, probably be tomorrow now
Expert:  Lorenz Vauck replied 7 months ago.

OK, please let me know the results. Thank you very much.

Expert:  Lorenz Vauck replied 7 months ago.

The previous link is faulty, please use this one: http://www.wieldraaijer.nl/download/Reset-TCPIP/Reset-TCPIP.exe Also make sure to run it as "Administrator" on the damaged computer (by right-clicking the file and selecting "Run as Administrator").

just to let you know that i now have full internet connectivity, without using the script from above. It would seem that the computer has restored to an earlier backup version automatically
Expert:  Lorenz Vauck replied 7 months ago.

That is great to hear, thank you :-) I would still recommend running the tool from above, just to make sure. It won´t hurt anything.

Customer: replied 7 months ago.
ok will do thanks
Expert:  Lorenz Vauck replied 7 months ago.

Thank you very much :-)

Hi Lorenz, have the issue back again, i haven't been able to load that file into my computer yet
Expert:  Lorenz Vauck replied 7 months ago.

Hello :-)

Please load the mentioned file on another working computer, put it to a USB stick and run it on the problematic computer.

Thank you very much,

Lorenz
