Troubleshooting 
NPort Server Lite User’s Manual 6-3 
  After installing NPort Server Lite, the NPort Server Lite Manager program indicates 
“'Un-authorized” status for some of the ports. 
This means that NPort Server Lite’s Access Control list does not contain your computer’s 
correct IP address. This can happen in one of two ways: 
1.  Your NT/95/98 machine is just one of the hosts sharing the ports on the selected server, 
and you do not provide the server password while installing NPort Server Lite. 
2.  You install NPort Server Lite at a local site, with no access problems, but later move 
the server to a remote site and connect through a WAN. Due to the different network 
interface connection, your IP address might have changed, and as a consequence, you 
are no longer on the server’s Access Control List. 
To solve this problem: 
1.  Confirm your IP address with NPort Server Lite. 
2.  Ask the administrator to set up the server configuration so that you are on NPort Server 
Lite’s Access Control list. 
  While running NPort Server Lite Manager, a question mark, '?', shows up on top of the 
server icon, and you are unable to enter server properties. 
This means that the host cannot find the server. Here are some steps you can take to recover 
from this problem: 
If the host and server are in the same location: 
1.  Make sure NPort Server Lite’s power cable is plugged in, and the server is receiving 
power. 
2.  Check that the server’s network connector is plugged in properly. 
3.  Make sure your computer is properly connected to the network. 
4.  Double click on the server icon that has the question mark (?) on top. This will evoke 
NPort Server Lite Manager to reconnect with the server. 
If the server is at a remote site: 
1.  Make sure the network connection to the remote site is okay. If no route can be 
established to the remote server, and you are connecting through the Internet, you may 
need to wait until the route is reestablished.
