You most likely have an AppleTalk Phase 1 versus Phase 2 conflict. The
NetWare for Macintosh VAP 1.1 only supports Phase 1. This prevents any
Phase 2 client from using the services.
Novell recommended a workaround. Upgrade to NetWare 2.2, and to the
Macintosh VAP version 2.2. This will provide the NetWare server with
AppleTalk Phase 2, and allow it to publish a LaserWriter printer queue that
Macintosh clients can use.
