"I recently learned something about NASes that buyers looking to use these products for database and other simultaneous-file-access applications should know about. The issue is how Opportunistic Locking ("oplocks") are handled."
"Opportunistic locks (oplocks) are a characteristic of theLAN Manager networking protocol implemented in the 32-Bit Windows family of operating system environments. Bascially, oplocks are guarantees made by a server for a shared logical volume to its clients. These guarantees inform the Client that a file's content will not be allowed to be changed by the server, or if some change is imminent, the client will be notified before the change is allowed to proceed."
"Office 2010 volume editions are delivered with the KMS client, which doesn't have to be installed. KMS clients will find the KMS host automatically through DNS."
