Looks like this might be a lonely troubleshoot, but here is more for anyone 
who may experience similar symptoms... (and of course any kind people who 
throw in a suggestion or two)

I have narrowed this down to what seems to be incompatable auth methods:
In XPsp2, I go to \\smbserver\fred - this shows either an empty folder, or an 
error (I have hide unreadable = on, so this may be the cause)
With konqueror, (smbclient -V: Version 3.0.15pre2-0.1-SUSE) i can go to 
smb:/user at smbserver - i get a user/pass dialog, and then i can see the 
directory fine!

Is my logic right? The xp clients are using some other kind of auth or 
connection than smbclient does?

The windows clients work ok, but it seems that the files they need to be chmod 
740 at least (700, 710 does not work, file owned by user.domain users)

Rather than play around with permissions (that worked before the trouble 
started) I would like to see what xpsp2 and smbclient do differently - please 
could anyone help with this?
