The problem is with my Autodesk Vault Professional 2013 (Server)

Hi Experts,
The problem is with my Autodesk Vault Professional 2013 (Server).
It shows an error message with an error code 1920. “Service 'MSSQL$AUTODESKVAULT' (MSSQL$AUTODESKVAULT) failed to start. Verify that you have sufficient privileges to start system services”-
I do not understand the error message. Please help me.
Thanks in advance.
