[Samba] Windows XP Machines (well mostly the XP ones) hanging

[James Jeffrey]

Hello Folks,

I will personally send $50(AU) of Pizza to anyone that solves this one :)

We have a network comprising approx 30 Windows workstations all logging in
to a samba machine running as a PDC. The main exported file system is an NFS
mounted file system, but this was happening back when this was an xfs file
system as well. ACL's are enabled. We are running Samba Version 2.2.8a. The
server does not appear overloaded.

Multiple users have reported that when they are trying to access files
across the network their machine hangs for approx 20 secs then continues as
normal. This does not happen every time, but does happen quite frequently.

Our network is not displaying a significant amount of packet loss.

Below is our Samba configuration.

James.
