TCP/IP > and LanMan can run concurrently over the same network (both CSMA/CD). With NDIS you can run multiple protocols over the same interface. The setup I use (which I think works pretty spiffy) is to use Microsofts NetBEUI protocol to do LanMan stuff, load and bind the NDIS to Packet driver interface, and then use packet driver based TCP/IP software (like PC/TCP or CUTCP) to do TCP/IP kinds of stuff. > >4> Does LAN manager provide file services to UNIX boxes via NFS or does > > it implement its own protocol ?

Actually the modular nature of LanMan allows you to use any one of a number of protocols. The ones I know of are NetBEUI, NBP, XNS, and TCP/IP. > >5> How does the allocation of resources work ?

LanMan resource serving is done from an OS/2 based system. For now that means that your server runs OS/2. There is third party software available to allow DOS machines to offer disk and printing resources to the rest of the LanMan clients. In the future if and when clients dump DOS and move to OS/2 then LanMan can start to look more and more like a peer to peer network because OS/2 workstations can then act as both a client server.

Now the real reason I replied to this article (sorry, I always get carried away). I understand that DEC Pathworks 4.0 is based on LanMan 2.0 code. I think it is not a full LM 2.0 implementation but it has been implied that if the TCP/IP transport is chosen for both the VMS side and the PC side then LanMan 2.0 client can connect to VMS Pathworks 4.0 server. I have not tried this but would love to hear from anyone who has. I like the LanMan product and think for larger LANs it has some strong features. It should be interesting to see how the market responds to LM 2.0 especially the Unix ports of LM 2.0 which are now showing up. I wonder if anything can slow the Novell juggernaut.
