Hi All,

An update to the original post on this subject:

When I initially copied the FDB file to the server from my laptop I
had had to log on as the server administrator. After doing this the
application on my laptop ran fine, even though the connection to the
server was disconnected/reconnected a few times.
When trying the app on the Win 2000 client it wouldn't work.
However, logging on to the server yesterday from the Win 200 machine
as administrator, and then trying the app now works.
Obviously I'm missing something here in terms of the necessity to
log onto the server in the first instance (the FDB is, BTW, in a
shared folder on the server).
Why logging on to the server just once should cause the app to run
from that point forward I don't understand. I had assumed (obviously
wrongly) that setting the port at 3050 would bypass the server log-
on requirements.
Actually, at the moment, the FDB is resident on the application
server which also runs a commercial Oracle based program (which in
turn is connected to a DB server). The Oracle program is still
under "development/modification" (for the last 10 months) so I am
trying to avoid any 'interference' with this aspect.
The one thing I haven't checked yet is what strain of Windows is
running on the application server at this time.
