"login attempt to the server below failed" for fms4.0

Hi,

I try to login admin console remotely, so I add a soft link for the "webroot" directory of fms to the appache default web host.

Then I could load the admin console page remotely, while when I input the server IP, username and password, it tries to make connection while reply back a message box saying that "login attempt to the server below failed!".

I really do not know how to resolve this issue. my 1111 port is opened in the firewall and selinux is disabled. I'm using centos 5.3 for FMS4.0.3.

Thanks.
