- I am responding to this because there seems to be a common misconception
- about NetBIOS. For some reason many people have this notion that NetBIOS
- is a protocol when, in fact, it is a programming interface. LAN Manager
- along with a lot of other PC network products "talks" to the NetBIOS
- programming interface. The actual protocol on the wire can be anything.
- Microsoft calls there NetBIOS protocol NetBEUI. Other protocols that can
- be used for NetBIOS transport include TCP/IP, OSI, XNS, NBP, IPX, and
- maybe some others. So when your network expert tells you NetBIOS isn't
- routable, or needs to be tunnelled, or says anything else about the format
- of the data on the wire without talking about the specific NetBIOS transport
- prototol then go find yourself another network expert. In the case of
- LAN Manager, Microsoft provides two protocols: 1) NetBEUI which is small,
- fast, and non-routable and 2) RFC1001/1002 TCP/IP NetBIOS which is, well,
- TCP/IP with all the rights and privileges that go along with IP. Note,
- there is no need to "tunnel" as with Novell. LAN Manager and other NOS's
- that use the NetBIOS interface can use any protocol they see fit from
- any of there favorite vendors like FTP Software, Wollongong, etc. Neat!

-
- With LAN Manager 2.1 Microsoft provides an IPX/SPX interface for your
- Novell redirector and stack to use along with the LAN Manager stack and
- redirector. It probably takes up a bit of memory when you get them all
- loaded but NDIS 2.0 supports dynamic loading and unloading of protocol
- stacks drivers can be moved in and out of memory as needed. I haven't
- actually tried it. I generally try to avoid Novell. But it looks pretty
- simple from the installation documents.
