[Samba] user nobody

[rob]

When my windoze 2K client tries to open some files, i get the following
message in smdb log:

[2003/10/01 16:00:42, 0] smbd/oplock.c:oplock_break(843)
  oplock_break: client failure in oplock break in file

/var/log/samba/log.smbd lines 33065-33087/33087 (END)


This results in a file taking 15+ seconds to open, does any one know why
windoze tries to connect as user nobody - especially when the share is
already connected and mapped as a drive with username / password and what
does oplock break mean?

thanks
