Windows Activition

I think Comodo blocks Windows 7 Enterprise 64bit activision. Windows gives error code: 0x8007232B. DNS name does not exist (more info). I am using Comodo’s ports.

Thank you!

What happens when you use another DNS server? Does the problem go away?

While you answer Eric’s Post You may want to Try to clear the DNS Cache
Start → Programs → Accessories → Command Prompts → ipconfig /flushdns

Kind Regards

I used this: http://www.sevenforums.com/tutorials/15037-dns-addressing-how-change-windows-7-a.html
Still it doesn’t work.
I put it back to optional.

I switched routers too (both are different).

If changing DNS servers and following Jacob’s advice to flush dns cache does not change the situation then it is either a firewall setting or a Windows error.

Can you show screenshots of the Firewall logs ( View Firewall events) and Defense + logs (View Defense + events) of around the time the windows activation error alert occurs?
