The computer detects that it is configured correctly but continually tries to obtain a DNS. System is a Windows 64 bit Home Premium Edition running Windows 7. I am running to a Cisco router by Hard wire not wireless. HughesNet is ISP. This problem is not stopping me from connecting to the internet; however, the event viewer log displays this as an error that can be corrected. I have disabled the Internet Protocol Version 6(TCP/IPv6). Doing that got rid of the errors in the event view log; but, when troubleshooting is ran on the network connection, the same message appears: Your computer appears to be correctly configured but the DNS server is not responding. Windows will continue to try to obtain a DNS. This is a problem simply because my Anti-Virus requires a constant DNS in order to have Real-Time protection. Panda is different from other anti-virus programs because it constantly updates where other anti-virus programs just update once after a computer is started. So if a DNS is not obtained at the exact moment Panda tries to update (which is all too often lately) the update is lost until I manually update, in turn which leaves my system vulnerable until a usable DNS is obtained. I am using the Internet Protocol Version 4(TCP/IPv4) and have tried just running the IPv6 but that led to no internet access. I have updated the Cisco router and therefore that is not the culprit. Cisco tech support assures me that it is a Microsoft problem because they do not have a workaround for Windows 7 based systems that share a router - Is there any validity to their claims that it is Microsoft's fault for not having software updates for internet connections? I have also read that if one of the computers that is hooked to the router is using Vista Ultimate, this sometimes causes an issue? True/False?
