Server: Novell does not support ARCNET adapters at the file server as of NetWare 4.11.
Client: 16-bit ARCNET drivers are supported by NetWare 4.11's Client 32. 32-bit ARCNET drivers are not supported.
In order to get ARCNET clients under Novell connected to a NetWare 4.11 file server, you need to have an IPX protocol router between the clients that use ARCNET and the Ethernet file server.
