Windows 8 will not resolve DNS

Hello,

I am running Windows 8, and am having trouble with DNS.

First of all, I have recently changed my modem setup from Dynamic IP, to Static IP, therefore, I have turned off DHCP, and assigned all computers individual IP Addresses.

I also own an Apple iPhone, and two other PC's.

These devices all work correctly with the same settings as specified in the Windows 8 PC. 

Here are the settings being specified:

IP Address - 10.1.1.5 (Changes for each device obviously)
Mask -255.255.255.0 
Gateway - 10.1.1.1

DNS:
Primary - 203.97.78.44
Secondary - 203.97.78.43

What I do not understand, is why my other PC's running on Windows 7, and my Apple iPhone, will connect to the internet with these settings, however, on my Windows 8 PC, I get a cannot resolve DNS error, whilst using any browser.

I have tried changing the DNS to several different hosts (eg. Google 8.8.8.8), and that has not worked.
I have flushed the DNS Cache, as well as restarted it.
I have also tried uninstalling the Wireless Networking Card.

None of these things seems to have worked. 

Can anyone help me solve this issue?

Can you ping the DNS host?
What if you change the IP of the Windows 8 machine to one that's working, does the problem still occur?

Run each of the commands below from the command prompt, what is the result of each? The result to look for is the "Non-authoritative answer" one.

nslookup technet.microsoft.com
nslookup msdn.microsoft.com 8.8.8.8
nslookup social.microsoft.com 203.97.78.44

If you can't fix it with duct tape, you haven't used enough.

Hey David, thanks for your response.

Attempts to ping the DNS results in a time-out.
I attempted to change the IP to one that had been confirmed working (10.1.1.3), and the same problem is still occouring.

Running those commands from the prompt resulted in:

DNS request timed out. (Time-out 2 Seconds)
Can't find address for server: technet.microsoft.com: Timed Out. 

The 8.8.8.8 One:
DNS Request timed out. (2 Seconds)
Server: Unknown
Address: 8.8.8.8

And a similar result for the 203.97.78.44 Command. 

I tried running these commands on my other Windows 7 Machines, and this worked.

Have you flushed the DNS cache?

Open an Administrator Command Prompt:

ipconfig /flushdns

I recommend to reboot your computer after this.  If your problem continues, the problem is not likely the DNS settings.

Hello Nate,

As stated in the question above, the DNS Cache has been flushed under an Administrative Prompt. 
The problem still persists.

The problem almost likely is DNS related, given that both the ping test and NS Lookup failed, given a DNS Timeout.

My apologies, I skimmed your original post.  What security software do you use?

No Problem :)

No security software is installed.

Windows Firewall is active on all my PC's (including the Win7 Machines).
I disabled the firewall temporarily on the Win8 Machine and restarted, to check if that was the problem, however, it did no help.

Was security software ever installed on this machine?

What happens if you allow the DNS to automatically be assigned?

Nope, security software has never been installed, aside from the Windows Firewall being enabled. 

The DNS cannot be automatically assigned, because the IP being set is static, not dymanic, therefore the option to automatically assign the DNS automatically is greyed out.

What I simply don't understand is that these exact same settings are being replicated on several different machines and devices (iPhone, PS3, 3 Different Windows 7 Machines), yet only Windows 8 is the one having the issue.

Well, this is a long shot, but you can try it anyways.

Open an administrator command prompt and type the following:

netsh int ip reset

netsh winsock reset

Were there any errors listed?  If not, go ahead and reboot the computer.  If so, let me know what those errors are.
