This is wrong:

should be
Path := 'C:\Program files\FPNet1\FPNet1_Data.fdb';

The DatabaseName property is 'andris:C:\Program files...etc. but don't set
it yourself.

Yes: I can see what the problem is. You have remote clients trying to use
Windows-local connect. Just fixing that Path property will do it. Don't
set DatabaseName - IBO will construct that for you.

Just one thing: do you have a default character set in your
database? Your TIBOTable would crash if you do, because you are not
setting the client character set here - or are you perhaps doing that
somewhere in the code, before connecting?
