¿Cannot change IP address or other server properties.

Therearetwosituationsthatcouldgiverisetothisproblem.

1.Password Mismatch – If you type the wrong password while running NPort Pro Manager, the Manager program automatically assumes that you are not the administrator. The administrator of the server is the only one allowed to modify the server’s configuration. Keep in mind that even when multiple hosts share the same server, access to the server’s administrative functions is still protected. If you need to change some configuration settings, you will have to ask your administrator for help. If you are the administrator but forget the password, you can erase the current password yourself by pressing the RESET key on NPort Server Pro’s back panel for three seconds.

2.Error Installation Type – You cannot change the server IP address if you are installing NPort Server Pro under Single-Host Mode. Setting the installation procedure up in this way makes the Single-Host Mode configuration procedure very similar to installing a traditional multi-port serial board. Under Single-Host Mode, users are only allowed to modify the server's name and password. This is because Single-Host users are not sharing their NPort Server Pro with other hosts. If you do need to modify other properties, run the setup program and change to another mode of operation (see Chapter 8 for details).

¿You would like to allow one more host to access your NPort Server Pro, but are unable to reach the page for Access Control.

1.Check the NPort Manager mode. If it is Single-Host Mode, reinstall it as either Multi- Host Mode or Custom Mode.

2.Double check your credentials to make sure that you are the administrator.

¿After installing NPort Server Pro, the NPort Pro Manager program indicates “'Un - authorized” status for some of the ports.

ThismeansthatNPortServerPro’sAccessControlListdoesnotcontainyourcomputer’scorrectIP address.Thiscanhappeninoneoftwoways:

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 Pro.

2.You install NPort Server Pro 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.
