I have a new SQL Server 2012 instance and when I run the following command I get an error.
ALTER SERVICE MASTER KEY REGENERATE
Msg 15329, Level 16, State 1, Line 1
The current master key cannot be decrypted. If this is a database master key, you should attempt to open it in the session before performing this operation. The FORCE option can be used to ignore this error and continue the operation but the data encrypted by the old master key will be lost.
When I try with the Force option I get:
The current master key cannot be decrypted. The error was ignored because the FORCE option was specified.
Msg 33096, Level 16, State 1, Line 1
A generic failure occurred during Service Master Key encryption or decryption.
