Windows 7: Win7 64 Home DNS failure

Win7 64 Home DNS failure

I'm not sure if this is the cause, or if it is a coincidence, but ever since I instaled internet explorer 9, I've been getting random DNS issues to where I can't surf the internet but I can still ping ip addresses, and anything I am currently connected to [yahoo messenger, AIM, steam, etc] is still connected but if I try to disconnect and reconnect, the connection fails.

Also, for a short period of time, a couple of days, I was able to get the DNS to work by manualy changing the DNS instead of letting the system do the lookup for itself.

So far, here is everything I've tried:

Uninstalled IE9, didn't help.
Changed the DNS lookup to google's DNS, worked occasionally but not anymore.
Changed the DNS lookup to OpenDNS's DNS, worked occasionally but not anymore.
Restarted router, worked some of the time.
Ran malware bites, spybot search and destroy, and norton antivirus [not at the same time] and found nothing.

I'm running out of ideas and could realy use some help on this problem.

One other thing that is very weird, I've tested my computer on a different, slower internet connection [house has a DSL and cable line, the cable is the one with the DNS issue aparently.] and it works on the DSL. BUT I'm on a borrowed laptop using my cable connection and it's working just fine.

I have Comcast Cable internet and I'm using a motorola surfboard extreme wireless cable modem gateway.

Edit:
I forgot to mention, on both tests and with the laptop that isn't having issues, I'm using a wired connection.

Thanks.

Hi Koden,
Have you tried flushing the DNS Cache. Run cmd.exe an administrator the type ipconfig /flushdns & hit enter.

Yeah, tried that. Forgot to mention it but yeah, I tried it. Seemed to do nothing.

I turned off a few programs that were connected to the internet last night and went to bed, woke up and it's working, but the problem is I'm /very/ sure it's going to die on me again. Here's my ipconfig /all information.

it may also be worth noting that I had Hamachi running but turned it off and disabled it just in case if that was causing a problem, didn't help at the time though.

It looks like I solved my problem. I think IE 9 had changed this service, "IKE and AuthIP IPsec Keying Modules" from manual off, to automatic on. After setting it to manual off and turning off the service, my DNS issue went away. It was fairly instant.
