Thank you very much again.
But still does not work.

I don't understand what "narrowest to widest" means.
My configrations are:
NIC 1(for firebird client):
IP addr 192.168.2.172
Submask 255.255.255.0


NIC 2:
IP addr 192.168.2.175
Submask 255.255.255.0

C:\Winnt\system32\drivers\etc\hosts:
127.0.0.1 localhost
192.168.2.172 fbserver
192.168.2.175 test

I tried to change IP adderss and submask to other value some times, but same
thing.
If you have any idea, please let me know.
Thank you in advance.
