Hi I currently have windows 7 home premium installed on my laptop. I have no problems with my internet connection as it works fine on my windows xp desktop. However, I keep on getting DNS error messages when trying to open a browser page on my laptop with Windows 7. I understand from reading other related posts that this could be a firewall Issue. However. I have tried disabling as well as uninstalling firewalls/ antivirus programs with firewalls and the problem still cannot be solved. Also, I understand that this could be an issue with the Microsoft Virtual WiFi Miniport Adapter, from reading previous posts. However, I do not see that listed under my Wirless ports. I was wondering if anyone could help me solve this problem? Thanks p.s. I also tried to ping and it was pining just fine with 0%loss.

To start, you may want to compare the IP config on both machines. Open a command prompt on each computer, and type IPCONFIG /ALL. The IPs should be similar (last octect is unique), same subnet mask, same default gateway and same DNS settings. Visit: anITKB.com, an IT Knowledge Base.

I did check with ipconfig /all and it does have the same subnet mask, same default gateway and same DNS settings.

Set aside the error message you see in Internet Explorer...thats not a good app to diagnose DNS issues. On the system having an issue, open a command prompt and type NSLOOKUP...hit enter. then type in names of host names and hit enter after each one...Is the DNS server resolving corretly? If so, this is most likely not a DNS issue. Aside from the local firewall...could you possibly have some blocking occuring at the permiter firewall (most likely your internet router)?

How can you tell if the DNS server is resolving correctly? In the command prompt after i typed in nslookup I typed in www.google.com and I got Non-authoritative answer: Name: www.google.com.cg.[nameofISP].net Address: ##.##.##.## and the address was the same for all of the websites i typed in, 5 in total If it is a blocking occuring in the perimeter router ( as you suggested possibily from the internet router) is there a way I can disable that to check? Because, I called my ISP the other day and they had me log on through safe mode and the DNS error was still occuring. Thanks

Hi Kristy, A nonauthoritative reply may indicates that the master server had a problem loading the zone, usually because of a syntax error in the zone data file. Check the server event viewer or syslog output for indications of a syntax error. Please refer to: Troubleshoot DNS http://technet.microsoft.com/en-us/library/bb726934.aspx If no clue found, I recommend use the Network Monitor to caputre the network traffice to find which happened.
