Hi Hellen,
[snip]
Errnr : 10061 WSAECONNREFUSED
Connection refused.
No connection could be made because the target machine actively refused it.
This usually results from trying to connect to a service that is inactive on
the foreign host - i.e. one with no server application running.

I would check :
Server :
1. Is the Firebird-Server running ?
2. Check the HOST file (no extention !!)
for a entry :

192.168.80.XX Firebird-Client
IP and Clientname depend on your network

3. Check the SERVICES file (no extention !!)
for a entry :

gds_db 3050/tcp # Firebird/InterBase Server

if it is the last entry make shure there follows
a linefeed after the entry

4. Make shure there is no firewall running
that blocks the port 3050.
5. Check the subnet-entries in your network-settings.
Make shure that Server and Client have similar entries.
6. Check log-file for new error-entries
7. make shure there is only one gds32.dll available

Client :
1. Check the HOST file (no extention !!)
for a entry :

192.168.80.10 Firebird-Server-Name
IP and Servername depend on your network

3. Check the SERVICES file (no extention !!)
for a entry :

gds_db 3050/tcp # Firebird/InterBase Server

if it is the last entry make shure there follows
a linefeed after the entry

4. Make shure there is no firewall running
that blocks the port 3050.
5. Check the subnet-entries in your network-settings.
Make shure that Server and Client have similar entries.
6. On ME turn off the SystemRecoveryFunction
7. Check log-file for new error-entries
8.make shure there is only one gds32.dll available

For more information refer the Operation Guide (OPGuide)
page 78 ff.

For connection use :
Servername:Server_drive:\Serverpath\Data.GDB
(drive and path on the server !!!! )
Don�t use mapped drives.

then it should work
