1. Make sure your app is loading the right client library. For Fb 1.5,
this is fbclient.dll, located in the \bin directory of the server
installation. The most likely thing is that you need to build the
"compatibility" version of the client - named gds32.dll and placed in the
client machine's system directory (..\system32 which is under WINNT on NT
and Win2k and under Windows on XP). The program for rebuilding the
compatible client is instclient.exe - in ../bin, docs in the \doc directory.
2. If the server is running under Linux then the connection string must be
TCP/IP and it is different to the one for Windows. Let's say the host
server is yourhost.com and the database is in /home/davidallan/data, here's
your connection string:
yourhost.com:/home/davidallan/data/MyDatabase.fdb
and on Linux it is CASE SENSITIVE all the way.
3. Make an entry in the HOSTS file of the client:
222.222.222.222 yourhost.com # IP address of the host server, of course!
4. Find out which port the provider is using for the gds_db service. If it
is not port 3050, you need to adjust the client's connection configuration
to poll the right port. See the Fb 1.5 release notes for a whole section
on this topic.
5. Firewalls, bad netmasks may also cause this error.
