A. It is possible to specify multiple NetBIOS names for a single machine as described in 'Q. How can I define multiple NetBIOS names for a machine?' however a bug in Windows NT 4.0 means only the MAIN NetBIOS name is used for print services.
When trying to connect to a printer hosted by an NT server from a client the error:
"Could not connect to printer: The printer name is invalid. "
will be displayed if the server name you are using is one of the servers Optional NetBIOS names.
To workaround this always make sure the 'printers' NetBIOS name is always the machines main NetBIOS name.
