Hi, I have installed Windows Server 2008 R2 Standard 68bit and activated that .... but later I found out that I had to activate RAID board as well. The Problem is, after merging to hard drive for RIAD 1 in my HP Proliant micro server and installing a fresh Windows Server 2008 R2 Standard 68bit I get this error to activation, Any idea how to solve the problem..... error number 0xC004C020 description: The activation server reported that Multiple Activation Key has exceeded its limit. /Eddie
