Strange, really strange for me.

I have two OSs on my PC. One is Server and the other is professional.
I always gets the response on the professional platform.

"Unable to complete network request to host "61.186.179.99".
Failed to establish a connection.

I use iboconsole to login the server(local,through local ip, either
127.0.0.1 or this referred above). and i assure that the server is
running.

the firewall has been closed.

I have reinstalled the firebird1.5.1 many times and felt a little tired.

Did anybody encounter the same thing?
