The installed server 2008 has OEM license on it, i don't now how it happened. Now when i try to install license and activate windows online with the purchased license it gives error. I downloaded windows server 2008 from torrent website and installed it on client's Server.
But i misplaced my windows media dvd of server 2008.
I purchased original windows server 2008 server standard addition Recently i undertaken a project of configuring domain in a office.
