The connection is being made and I am sure that the connection
string is correct. I'm pretty sure that there must be something
blocking port 3050 on Windows 2003 because the server cannot even
talk to the firebird server itself.
I have seen the same issue on a windows 2000 machine running windows
2000 server, with the exception that the server could talk to itself
but clients could not.
In this case I was able to get the client talking using a netbeui
connection. I may have to try the same on the Windows 2003 server.
