[Samba] Problems w/long file access times (samba2.2.5 & WinXP pro) (fwd)

[Karim 'Kasi Mir' Senoucci]

Hello all,
we're currently having problems with Windows XP machines that have
*very* long file access times for files that are located on our
linux-based samba server (samba 2.2.5 / linux 2.4.18). This happens with
all kinds of files, with all kinds of programs, including Office97, text
editors, develoment environments, etc.

Sometimes - the incidents itself seems to be random and is not
reproducible so far - a program freezes after a file to be opened or
saved is selected; depending on the program, it either

- returns after a minute or so claiming the operation has failed, only
  to load/save the file successfully anyway most of the time, or

- loads/saves the file as requested and unfreezes the program after up
  to 60 seconds.

This only happens with our WinXP clients; the two legacy Win98 machines
still in use don't ever complain about anything. I read something about
oplock problems in an older mail on one of the samba mailing lists and
tried tinkering with the parameters to no avail.

Below, I include my smb.conf; a debug logs are available on request. Any
help or insight into the matter is appreciated.

Thanks
Kasi Mir
