I have just updated to BIND 9.9.3 (by stopping server, deleting old binaries and copying in new, then restarting; my usual update method); however, it is now hit or miss whether a net start command actually does start the server. ('Restarting' via services.msc is also unreliable.) Anyone else finding this a problem?

Have reverted to previous version meantime (by same method) - no problem.

With thanks.
