AW: [Samba] user can't shut down windows clients?

[ksc133]

hi matt,

sorry to bother u again.

i followed your instructions to create a domain user group GID -513
and assign all my users to that group.
but to my dismay, i still can't work?
i add domain user group = username1, to my smb.conf but still can't work?
then i changed all my users to the wheel group = power users. but also 
cannot?

is this a problem with win2k o/s rather than samba?
thanks Q
