The properties of SQL server
service are incorrect. Remedy:
Check the properties of
the SQL Server start-up service in Services
in Control Panel are correct. SQL Server
will not start automatically unless the
service is set to automatic start.

used to run the SQL Server service is
correct. Try to start the SQL Server
process, if a logon error is returned
then either the account or password
specified is invalid.
The SQL server files are corrupt.

If the SQL server files
are corrupt reinstall SQL server.
