Ok, I made a posting a couple of weeks ago about firebird not always
starting up quickly enough after logging in.

We have some applications that have to launch on a completely
unattended terminal PC. We occasionally get a problem whereby our app
will try to connect, but the firebird server returns an error along
the lines of 'No Read/Write access to Database file xxxx.gdb'. Our
app already checks for a running process called 'Firebird Server' or
whatever, and that check get passed. If you just OK or Cancel on that
message and try again, it's fine.

Firebird IS running as a service, but we're checking the box for 'Use
the Guardian to control the service' when installing.

So could this problem be caused by using the guardian? It's a real
pain, becuase it can't be reliably repeated.
