connection problems

[Brian Hawley]

I'm running a Redhat Linux 6.1 server with Samba 2.0.7 and 7 Win95/98 
clients connected through a brand new 10/100 switch.  We thought that 
the problem was being caused by too much traffic for our old hub to 
handle but the the switch has had no effect.

My users have been having a lot of trouble logging in and mapping 
Samba shares on Windows 9x. (we map the /server/homes directory to 
p: and /server/docs directory to z: with "net use p: \\server\homes 
/yes")

If everyone logs on at relatively the same time (which they do) only 
the first person to log on gets their mappings (sometimes).  Everyone 
else fails.  The problem is inconsistent.  Sometimes no one gets a 
drive mapping.  Sometimes a couple people get one mapping, etc.

The win9x machines are set to share-level access control, not logging 
onto a WinNT domain, quick logon, primary network logon is Windows 
logon, all set to 10 Mbps half-duplex, subnet 255.255.255.0, Wins 
server points to the server, gateway points to the server, dns host 
is user name, domain is our isp, domain servers point to our isp, 
workgroup is "workgroup".

The server is registering on the switch as 100 Mbps full-duplex.  I 
don't know if that makes a difference.
