On my Samba 3.0.11 installation (which should act as a WINS server), the "wins 
support" option ignored. (3.0.10 on a different machine is ok). Yes, I have 
checked for typos and re-typed it several times.

I have set "wins support = yes", but it does not appear in the output of 
testparm. "testparm -v" shows "wins support = no", and I get tons of "error - 
should be sent to WINS server" in my nmbd log.

Unfortunately, I added the option after the upgrade to 3.0.11, so I can't tell 
if earlier verions on the same machine would be affected.

The following is the "globals" section of my testparm output (note the absence 
of the "wins suport" option):
