Hi,
I had the same problems you descripted but here it's all good now :)
Running samba 2.2.5 as PDC for 475+ WinXP clients, each using 6 shares
at least.

So far so good...

Same here last week.

Got ya... change that to:
socket options = SO_KEEPALIVE TCP_NODELAY
read raw = Yes
write raw = Yes
And make sure your OS's tcp-stack tcp time wait interval is lowered:
On SunOS it's configured with ndd -set /dev/tcp :
TCP_CLOSE_WAIT_INTERVAL=30000
On Linux it's configured with /etc/sysctl.conf / sysctl -p
net.ipv4.tcp_keepalive_time = 5000 <-- Play with this and do netstat
-an | grep "WAIT" | wc -l (must be low)
net.ipv4.tcp_fin_timeout = 30
Goodluck,
