This section discusses special issues raised when running NPL on a network in which more than one topology is involved, commonly referred to as a "mixed network".
When running NPL on a peer-to-peer network attached to a Novell network, it is necessary to use a "Supported Networks" instead of a "NetBIOS" RunTime. Even though NPL may only be running in the "NetBIOS environment", NPL will "see" the Novell network. A "NetBIOS" RunTime will return the error:
This RunTime is not authorized for use with Netware
In a mixed environment if the workstation is logged on to the Novell network the RunTime will attempt to authenticate from Novell. If that fails, the RunTime will attempt to authenticate using the NetBIOS layer.
When running NPL on a network with both Novell and NT servers, it is necessary to use a "Supported Networks" RunTime instead of a "NetBIOS" RunTime. Even though NPL may be located on the NT server, NPL will "see" the Novell network and attempt to authenticate from it. A NetBIOS RunTime will return the error:
This RunTime is not authorized for use with NetWare
when trying to run in this environment.
In a mixed network environment if the workstation is not logged on to the Novell server but is logged onto the NT server the RunTime will attempt to use Novell for file locking and to track user counts. If the authentication process fails in the Novell environment or the workstation is not logged in to the Novell server, the Windows RunTime will return the message:
Click on the OK button. The RunTime will attempt to authenticate from the NetBIOS layer.
This warning message can be suppressed in the windows RunTime by adding
WarnNovellNoLogin=1
to the [GENERAL] section of RTIWIN.INI.
