TCP/IP setting on windows 8 reverting back to automatic

Hi,
Here at work we need to set a particular DNS addresses for our internet to work.
All of our computers' network adapters have the Obtain IP address automatically checked, and use the following DNS servers:
122.49.191.252
122.49.191.253
(Adam internet, for those of you in Adelaide )
However, there is one particular Windows 8 Laptop that no matter what we do, reverts back to "get the DNS automatically." which makes the internet not work on there.
What is bizzare is that during the morning and day it is OK and around 5PM it starts to cut off. Not sure if this has anything to do with peak users or Adam Internet but that is beside the point.

How can we fix this TCP/IP properties issue?
We run it off a dynadock so initially I thought it was that adapter somehow reverting back to original setting, But I tried the DNS setting on the onboard adapter and also the WiFi adapter, and they all go back to automatic setting, as soon as you click OK and Close.

Please help!
Thanks :thumb:

My initial thought is (and I've just woken up so...) it's a piece of software that's being run or is running in the background that is resetting the DNS information.

have you tried running it in safe mode , setting the DNS in the period you usually have issues and see if then resets back ?

Why don't you just set the router's dns servers in WAN settings as those addresses and then enable dns relay in it?

What that will do is make the machines' dns queries go to the router and the router will auto pass it to that primary dns you've set or fallback to the second you've set (for instance, the addresses you've shown.)

You won't have to worry about each individual machine this way.

The problem though that you're saying, is that you can't specify a particular dns server if the adapter is not set as a static one. For example, you are relying on the DHCP server of the router to pull ip addresses. That won't work. My above solution regarding router settings will.

I doubt that IT would be happy if you mess with the router config.
However there are GPO (DNSClient) options and settings in the registry related to persistent DNS servers setup.

As I read it, Cookie IS IT. heh heh :) The clue: "there is one particular Windows 8 Laptop that no matter what we do,"

so for one laptop he should change whole network config? Doubt it. The problem with system reverting to old network setup in windows is pretty well known, just need to co clear registry and or GPO. This may be something else too, but seems lakie easy step to check for the remnants of old configuration.

No, he should change it so all laptops can work:

Yes, I AM IT :) ...well graphic designer/web developer and by default (the IT guy....) and yes the problem is only happening to that one laptop.

I have tried to set the DNS in the router but it's never worked, so I ended up setting each and every machine as we didn't have time to fix the problem. Maybe I haven't "enabled the dns relay" option...which I will look at now.
The problem is only happening with one win8 laptop. We have 5 machines on win8 and another laptop which is win8 which holds the setting.

So my plan of attack is:

1. Investigate the software that's being run or is running in the background that is resetting the DNS information.
2. Investigate the router settings to enable the dns relay

All fixed, just reformatted win8. Would have been faster than trying to figure out what it was...
Thanks to all :dinesh:
