the user is still working on the XP machine!

Thank you John for the reply.
I fixed it by myself:
I just move 'root postexec' option from [netlogon] to [homes],
(everybody has a home directory)
and just leave 'root preexec' option in [netlogon].

I don't understand why [netlogon] service gets disconnected
after around 11minutes on samba 3.4.5 and 3.0.28.
but it doesn't happen on samba 3.0.22.
