Samba 2.0.x unusable for this environment

[Jay Anderson]

I just attempted to upgrade from Samba 1.9.18p10 to Samba 2.0.4b, and I
have had to revert to 1.9.18p10 in less than a day.  I attempted to
upgrade to 2.0.1 back in January, and had to back off as well.  I was
hoping the problems I saw then would be resolved in 2.0.4b.  I sent a
message to this list back in January or February as well, but saw no
responses.

My environment is about 210 Win95 PCs (with a few NT 4.0 workstations
thrown in) and 6 MetaFrame servers (SP4).  I compiled Samba on Solaris
2.6 using gcc 2.8.1, and I am running it on a Sun Ultra-1 with Solaris
2.6.  The network connection is 100BaseTX.  The Samba server is acting
only as a conduit, there are no local data filesystems; all shared
directories are NFS mounted filesystems.  The problems and symptoms that
caused me to back off the new version of Samba were:

- occasional error on saving file to Samba share resulting in corruption
(mainly from PCs)
- printing problems; no output, or corrupt print jobs hanging printers
- each MetaFrame server would have only a single smbd process, instead
of a separate smbd process for every user, as with Samba 1.9.18p10

I ran Samba 2.0.3 and 2.0.4 and 2.0.4b on a test server with up to four
users with no problems.

I use "security = user" for Samba 1.9.18p10.  Last January I tried
running with "security = domain," but this time I thought I'd try
changing one thing at a time, so I ran with "security = user."

I am attaching the global section and representative shares from my
smb.conf.  Sure would appreciate some ideas on what is going wrong.
Samba 2.0 is unusable for me until I can resolve these issues.
