Bug #: 33642
           Summary: Microsoft SQL Server Management Studio Express 2005:
                    restarting SQL server fails randomly
           Product: Wine
           Version: 1.5.30
          Platform: x86
               URL: http://www.microsoft.com/download/en/details.aspx?id=8
                    961
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wmi&wbemprox
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Now that Bug #33607 is out of the way, it is possible to restart SQL Server
service. The application first stops the service, then checks if it is stopped,
and if it is, tries to start it. Starting the service quite often throws an
exception, and stack trace reported by the application points to wbemprox.
> From the initial investigation it seems to me that calling StartService

temporarily invalidates all existing instances of the service object. Here one
thread tries to get SystemName property from the object while another thread
tries to restart the service, and getting property throws an exception.
