i want to activate my windows online but its giving following error a problem occurred when windows tried to activate. Error code 0x8007232A

Error code 0x8007232A Symptom When you try to use a KMS host to activate one or more computers, you may receive the following error message: 0x8007232ADNS server failure. Cause This issue may occur if the system is experiencing either a network issue or a Domain Name System (DNS) issue.

Where did you obtain this server and its product key? The server is obviously trying to activate to a KMS server, not to the Microsoft activation servers over the Internet. Is it an MSDN MAK key?Bill
