I have noticed that PC-NFS 3.5 does not support the "net join" command that
was supported in previous versions of the software. Why was this function
removed from the new release?
With 3.0.1 I am able to do something like this:
net use g: \\servboy\
net use h: \\servboy\home
net use i: \\servboy\usr
net join g:\home h:
net join g:\usr i:
to make all of the filesystems for a server available under a single
network drive (G:).
Does anyone know of a work around that will allow me to do the same thing
using version 3.5?

Quoth jeff@com50.c2s.mn.org (Jeffery S. Wilson) (in <1991Jun5.223101.17798@com50.c2s.mn.org>): #I have noticed that PC-NFS 3.5 does not support the "net join" command that #was supported in previous versions of the software. Why was this function #removed from the new release? This observation is correct. The NET JOIN functionality was removed because it was incompatible with the revisions to the mounted drive state required for MS Windows support. Windows maintains the context of each of its subprocesses by exploiting the fact that DOS maintains all of the state in a single, swappable data structure. This structure includes the Current Directory Structure (CDS, sometimes referred to as the Logical Drive Table, or LDT). The CDS records the state of each drive (up to LASTDRIVE, and the current directory for that drive. For speed, we store both the path (as does DOS) and also a handle for the cached filehandle corresponding to the directory. There's not enough spare bits to encode the possibility that this filehandle is relative to some JOINed drive rather than the root drive. We could have given up on the idea of caching the directory file handle and walked the full path on every access, but this was (1) slow, and (2) would have required a major rework. So we had to sacrifice NET JOIN. The only benefit is that we thereby freed up enough space in a fixed-length table to increase the number of mountable drives and printers from 8 to 14. For more information on all of this, let me recommend "Undocumented DOS", which lays bare the guts of DOS in a manner reminiscent of the pioneering anatomists depicted in Flemish paintings..... -- Geoff Arnold, PC-NFS architect, Sun Microsystems.
