samba - Jul 2003 - Delay opening Word, Excel files

Hello,

I am running samba 2.2.7a on Red Hat 9. The clients are running Win2k with
SP3 and Office XP with SP2. The Samba server authenticates with a WinNT 4
domain controller. 

When the users open a Word or Excel document there is a 30sec delay before
the file opens. From info gleaned from searches on this subject I have tried
turning oplocks off altogether, which resulted in Word and Excel crashing
whenever I tried to open a file. I also tried setting oplock break wait time
= 10 which had no effect.

Thanks in advance for any help you could give me!

In the smbd log I see the following:

[2003/06/29 04:23:01, 0] smbd/oplock_linux.c:linux_init_kernel_oplocks(287)
  Failed to setup RT_SIGNAL_LEASE handler

and occasionally:

[2003/07/01 04:02:03, 0] param/loadparm.c:map_parameter(2077)
  Unknown parameter encountered: "revalidate"
[2003/07/01 04:02:03, 0] param/loadparm.c:lp_do_parameter(2752)
  Ignoring unknown parameter "revalidate"
