I am not sure if your problem is similar to what we have just experienced.
we are using samba 2.2.3a-12.3 on debian with winxp sp1 clients
we are using roaming profiles
first logon after reboot fails sortof
Windows cannot find a server copy of roaming profile will logon with
local profile
funny thing we never saw any activity in hostname.log (seperate smb.log
for each machine)
smbstatus showed connections there
we also had the problem if winxp screen saver came on (ie inactive for
15mins or so) the network shares would fail nextime you tried to access
them. SOmetimes would reapppear after 3 or 4 tries sometimes required
logoff and back on
we included a deadtime = 1 to the smb.conf
both problems seem to be fixed now. Have spent the afternoon testing and
cant repeat the error.
maybe you could try it
