Consider the following scenario:
  • You are using Microsoft Azure cloud service.
  • You create two VM nodes by using the same Microsoft SQL Server 2008 R2 galley image.
  • You run the following query in SQL Server on each VM node:
    select name, key_guid from sys.symmetric_keys where name = '##MS_ServiceMasterKey##' 
In this scenario, the query returns the same key_guid value that represents Service Master Key, which is expected to be unique for each VM node.
