couldn't set effective gid to 100

I'm experiencing this same problem with two installations of samba 2.0.3 on
the same domain. I have discovered that if I do not start the daemons using
the /etc/rc file at boot time but launch them when I log on as root samba
works fine. Otherwise if they are launched at boot time, no amount of
stopping and starting will help, samba will not work at all.To be honest,
this baffles me and I would like to know if there is a way of starting the
daemons at boot time without encountering this error. 

Thanks all for the help.  I guess being lazy doesn't pay sometimes.  I
that if slackware was distributing a binary, that it actually might work. 
downloaded and installed 2.0.7, and it solved my problems.

Thanks again...

PS, The version of Slackware that I am running comes with 2.0.3...
