u
NPort Manager showing '?' on top of the server. And, the server cannot to
enter into server properties.
This means the server cannot be found under this environment. There are some
steps to recover from this problem:
If at local site and the server still exists:
1. Check if your server is powered on.
2. Check if the network connector is plugged in properly.
3. Check if your computer is connected to network properly.
4. Double click on the server with '!'. This will evoke NPort Manager to connect
with the server again.
If the server is at remote site:
1. Check if the connection to remote is running ok. If no route to remote server
and you are connecting through Internet, you may need to wait till the route is
recovered.
2. If the route is ok, try to run 'ping server-IP-address'. If the server cannot be
pinged, you may have to ask a worker at remote site to check if the power is on
the connection is ok and double click on the server with '!'. This will evoke
NPort Manager to connect with the server again.
If the problem still occurs, you may consult with Moxa technical support for
further information.

You cannot find the server after your Windows NT being rebooted.
u
You have changed the server from duplicated IP address. However, after
you turn off the server and restart it the next day. You cannot find the
server. When you try to add it again, the IP address duplication comes up
again.

You can find the server after Windows NT restarted. Sometimes you
cannot access to the ports.
You might have a DHCP server on your network. DHCP server may assign IP
address to you host automatically. It breaks the security access rule between NPort
Server with it Windows NT host. And, NPort Server do not act as an DHCP client,
it might assign the same IP address to other DHCP client. To conquer this problem,
you should:
1. Consult with the administrator of your DHCP server to give you a dedicated IP
address of both your Windows NT and the NPort Server. He should set the
exception to your DHCP server.
