Windows 7: DNS_C protocol causes lag spikes every 10-20 seconds

DNS_C protocol causes lag spikes every 10-20 seconds

Guys this is really annoying especially when I am on ts/playing online, I have noticed that svchost.exe is doing this connections every 10-20 seconds, and every 10-20 seconds there is a lag spike that jump the latency up to 1000ms and more.

I want to disabled this periodical connections that windows does...I don't know what Has caused this...I have tried completely disabling svchost.exe access to internet but than no application launched can connect to internet.

The connections are port specific, the remote ip to which it connects to is always, which for sure is the ip of the dns (redirected by the router) plus the port 53. I have tried completely disabling the access to this remote port for all the local ip and local ports with my firewall, but it just keeps avoiding it. I have used this method with the connections to microsoft with the port 3544 witch are being disabled.

Still I can't find I way to avoid this hateful lag spikes every 10-20seconds, they are really annoying! help, thanks.

RC hangs ~every 4 seconds for about 2-3 seconds
Pretty much the title here. Except sometimes it will work just fine if I'm not doing too much. The startup also hangs after the splash logo to the login screen for about 10 seconds. In build 7000, there was no lag at all. Any ideas? Driver suggestions? Not sure.... Thanks!
