my Samba installation (see below) is
* _very slow_ during logon from a Win XP Workstation,
* one Workstation produces a _high load_ of 97% on the server for ~10
secs on a P4 2.4Ghz 512MB RAM system
* makes it impossible to use _redirected folders_, because stupid
Offline Files and syncronisation kicks in.
Can you help me?
Now to the _details_:
I am running Samba 2.2.8a on a Debian Woody server (P4 2.4 Ghz, 512MB
RAM, IDE RAID) which uses OpenLDAP 2.0.23 as database backend. All on a
User login (encrypted passwords), adding workstation to domain, normal
file sharing, getting Default Profile for new users, running logon
script works all great, but
during login of a user to a Workstation the process is very slow. The
default profile which gets copied is just 8MB, so its not data transfer
which is slowing it down.
Also when a users logs in on the samba server the load rises to 97%.
This is just on a setup with one server and one workstation. I am
planning of deploying 60 clients which will apparently not work with
I have now clue on how to trace the problem. Can you help?
Third problem is with the roaming profiles. The profiles itself work
great, just I wish to redirect the Personal folder. I read the HowTo on
the SambaDocuWebpage finding the UserShellFolder directive. I did a
NTConfig.POL file with poledit.exe setting this folder to
%LOGONSERVER%\%USERNAME% and also setting some permission stuff.
The file gets read because the permission stuff is done and the Personal
Folder is redirected to the users homedrive on the samba server, BUT
this activates the OfflineFiles mode of WinXP and WinXP tries to
syncronize the files on users logoff.
I found a way to prevent this by setting in some NetCache registry
values the "Enabled" switch to 0, so the syncronisation doesnt take
place but still the Personal Folder will carry the symbol of a folder
were syncronisation is enabled. Also WinXP seems to transfer constant
data with the samba server which increases network and cpu load.
Is there a better way of doing it?
Is there a better way of doing policies than poledit.exe?
On sambaXP many people spoke about the new Samba Howto. Which one is it?
Is it already released?
Thank you in advance
P.S.: Do I see it correctly that the GPO on a Win2000/XP ADS setup are
just specific NTConfig.POL files applied to a special workstation or
group of workstations?
