I have recently installed Samba for the first time. My server is a Dell
PowerEdge 300 running Mandrake Linux 7.2. I installed Samba from the
Mandrake CD and upgraded the RPMs from the Mandrake update site. My client
computers are Windows 2000 Professional computers.
I believe that I have correctly configured Samba, as I have been able to
get files from all three of my client computers. My smb.conf settings
follow below (leaving out most comments and settings related to printing):

However, I have experienced a strange problem where only one computer could
log in at a time. Other computers would not be able to browse the network
at all. After some digging and running diagnostics, I have concluded that
the problem is with the shared memory accesses. My smb.log file
(diagnostics level 3) follows:

ERROR: Failed to initialise share modes
My questions are:
1. Is this a problem with the program, or with the RPM compilation of the
program?
2. Increasing the shared mem size from 1 mb to 5 mb alleviated the problem
somewhat. With 1 mb, I could only connect 1 computer before subsequent
connections failed. With 5 mb, I got up to 3 computers before the fourth
connection failed. What is a reasonable shared mem size? The man file says
"Set to 5 mb for a large number of files". If I can only support 3
computers with 5 mb, how much should I be allocating to scale up to 10
computers (or more)?
Any advice would be most appreciated.
