Yes!  Or more accurately, similar problem(s) but different.  ;-)

I've had problems with Win9x boxes locking files they shouldn't since 
moving to the 2.0.x series from good 'ol 1.9.18.  Two examples would be:

1) I have a "netlogon-adm" share for modifying client login scripts, 
available to the admins only.  Sometimes when accessing this share it will 
hang for 20-30 seconds and I can see "oplock release" error messages in the 
samba logfiles.  I know that no one else is using the share and since the 
regular "netlogon" share is set "share modes = no", clients using it 
*shouldn't* be locking files.

2) CD-ROM databases copied to hard disk and set "read only = yes" and 
"share modes = no".  I get similar results as in example #1, especially on 
.exe files.

This sounds like just what the Doctor ordered to fix a nagging problem!

Perhaps code could be added to testparm that would issue a warning when 
"share modes = no" and "read only = no"?  Granted not all applications will 
want "read only = yes" which is why I suggested a warning only.  To quote 
Jeremy, I certainly wouldn't want to deprive people of the opportunity to 
"destroy your files using the windows applications of your choice..."  ;-)

When will 2.2.3 be available for consumption in RPM format for RedHat 6.x 
and 7.x?  I have resisted the temptation to install software via non-RPM 
methods on my production servers and would like to continue to do so.

Thanks Jeremy!
