Installation and Configuration Troubleshooting
u
Cannot Access from the first computer who install the Single-Host NPort
Manager
For security and simplicity, the 'Single-Host' type allows only one host to connect
to the NPort server. Thus, while you are using the single-host type of installation
and you find the server being configured before - with password protection, it is
advised that you stop and think if you really want to add the second NT host as
single-host type. If your application is for Multi-Host, you need to install the
NPort server under Multi-Host.
u
Cannot change IP address or other server properties.
There are two possible reasons that might evoke this problem.
1. Password Mismatch - If you type in a wrong password while NPort manager
asks for password checking, you are telling the NPort Manager program that
you are not the administrator. If you are not the administrator of the server, you
cannot make any modification to the server. Since the server may be shared to
multiple hosts, the access control is protected. If you do need to change some
configuration settings of the server, ask your administrator to do so. If you are
the administrator but forget the password, please contact with Moxa to recover
your system accessing capability.
