NT does not handle this properly. Service granular dependency is not 
even descriptive enough to cope properly with the needs of the services 
of a plain Exchange server. That's why you get mysterious warnings and 
errors in the event log that are not warnings and errors. I think 
feature granular dependency is required, IMHO, which requires that 
services all just start and block early, either on IO, or waiting for 
the features they depend on to start.

It means dependencies can be discovered from service configurations 
rather than being statically conservative, and parallelism is used to 
the utmost.
