You can't control Windows - it pleases itself about how long it takes to up
the service. As far as the client is concerned, no service means
unavailable database.

But your application's connection procedure can easily intercept the
"unavailable database" message in a while-not loop, with a timeout
loop-breaker in case connect errors come from network or other external faults.
