Dear all, In our Data Center, we have around 100, 2008 R2 windows servers. Currently we have MAK key for licensing. Our client does not want to connect the servers to internet because of some security reason. My question is is it possible to activate all the servers using MAK or we have to install KMS server? Please help me!!!!!!!!

Hello Kumar, I suggest you check this guide once:http://technet.microsoft.com/en-us/library/cc303280.aspx#_Convert_KMS_Clients KMS vs MAK:http://social.technet.microsoft.com/Forums/en-US/itprovistaactivation/thread/fd0a37a9-a260-4789-b400-b4f2e134916aRegards, Ravikumar P

Hello, you cannot activate MAK with a KMS server, this requires KMS key. Without internet you can do activation with telephone.
