Memory Problems

[Chris Tooley]

I have a Samba server running on RedHat 6.0 (Samba 2.0.5a).  The server is a
dual 233 with 192 meg of RAM and it is constantly choking on memory.  It is
running several other servers (sendmail, apache, mysql, openldap, and Knox's
Arkeia Backup Server) but if samba isn't running I max out at about 50-58
meg of memory used, but if smbd and nmbd are running it hits about 185-188
meg of memory used, with about 45 meg of that being cached memory.  I have
about 30 Windows 95 workstations, 10 Windows 98, 1 Windows 2000
Professional, and 2 Windows NT workstations, logging in with
PlainTextPasswords.  How much memory should this be using and if I need more
what should I put in the machine.  With only 3 DIMM slots, I don't want to
have to keep buying memory, I just want to get it and be done.

Also, I'm having a problem with some machines trying to log into the domain.
They say that there is no domain server available and don't log into a
domain.  But the first time they try to connect to a network share it logs
into domain and runs the script.  Is there a way ensure the connection when
the user logs in?

Any help would be appreciated.
