When you use the iSeries NetServer™ guest support to access iSeries output queues, you may experience trouble when trying to access the server. In addition, your specified printer may not go online. If this is the case, you must add a password to the iSeries NetServer guest user profile, SMBGUEST, for example. You must also ensure that you enable the user profile. The Network Print Server (NPS) requires a password for authentication although it will not prompt the user to enter a password.
The addition of a password in the SMBGUEST user profile does not affect users who access iSeries NetServer file and print shares. When a user requires guest support for file and print services, iSeries NetServer does not prompt the user for the SMBGUEST password. Because the SMBGUEST user profile has a password and is enabled, set the initial menu parameter to *SIGNOFF, INLMNU(*SIGNOFF), to deny signon access.
