yeah, meant 3.0.x, sorry about the.

this is how my filesystem is setup.

( On server1 ) 
sambaserver	= /home/samba/datadir/  ( PDC + ACL + ea ) Kernel 2.6.18-4 (
debian )	
		 Datadir is shared, this is my global data folder for users.
Sambausers		/users/		The users personal folder
nfslinked	/home/users/userfolder/"symlinked folder to a
XXXX1/subfolder"       ( this folder comes from sco unix 5.0.7 NFS V2 ) 

nfsmount	/home/nfsmount/XXXXX1	nfs mounted folder, shared in
sambaserver als XXXX1 ( i have 3 of these folders )  ( chmod 777 ) 
nfslinked2	/home/nfsmount/XXXXX2	nfsmounted folder on debian etch,
linked in "Datadir" as temp folder "chmod 777" is used.

( UNIX ) 
mounted the user home dir from debian in /u/ 

dont ask why but im have lots of cross server scripts running here.
And still expanding..

i created 1 "nfs user" on the debian server, i gave these the same UID/GID
as on my unix server
saved problems with rights.

in samba i forced these users so these are always the unix user.
this is not done in the nfslinked folders. these are users personal folders.

on my WXP sp3 im running Mcafee 8.5 Enterprise Patch 5.

Are you aware it could also be a problem in the virusscanner your using? 

Hope this info helps a bit.

here a part of my settings.
        map hidden = no
        map system = no
