Hi all, Ubuntu 8.04 Server 64-bit edition Samba 3.0.28a configured as PDC I have NO WINDOWS NT MACHINE ON THE NETWORK. WinXP clients login to the samba domain and access their home directories as configured. I am following the instructions in http://www.samba.org/samba/docs/man/...#magicnetlogon to add domain users to the winxp clients Power Users group. Code: #!/bin/bash /usr/bin/net rpc group addmem "Power Users" "DOMAIN_NAME\$1" \ -UAdministrator%secret -S $2 exit 0 [netlogon] comment = Netlogon Share path = /export/samba/logon root preexec = /etc/samba/scripts/autopoweruser.sh %U %m read only = Yes guest ok = Yes I tried executing the net rpc group addmem command manually and here's what happens #net rpc group addmem "Administrators" "Domain Users" \ -S WINPCO32 Password: Usage: 'net rpc group addmem <group> <member> root@sunbox:~# net rpc group addmem "Power Users" "domain_name\username" Password: Could not add domain_name\username to Power Users:NT_STATUS_NO_SUCH_ALIAS (I replaced the domain_name with the name of the domain and username with the appropriate user account.) #net rpc group addmem "Power Users" "Domain Users" -S 100.100.100.247 Password: Could not add Domain Users to Power Users: NT_STATUS_ACCESS_DENIED where 100.100.100.247 is the clients machine IP address How can i make this work?
