Hi, I'm running samba 2.2.3a as PDC and the two global groups 'Domain Admins' and 'Domain Users' did work some time ago. I don't know since when, but now only 'Domain Admins' shows up in the usermanager of XP and win2k. In XP 'Domain Users' is replaced by Unix.group.nnnnnnnn, in win2k it is completely missing. On the console 'Domain Users' becomes some cryptic chars: X:\>net group /DOMAIN The request will be processed at a domain controller for domain DEMAG Group Accounts for \\PDC --------------------------------------------------------------------- *?? *Domain Admins The command completed successfully. An equal search from a linux box brings the expected result: $>rpcclient //pdc -U martink -c "enumdomgroups" Domain=[DOMAIN] OS=[Unix] Server=[Samba 2.2.3a] cmd = enumdomgroups enumdomgroups group:[Domain Admins] rid:[0x200] group:[Domain Users] rid:[0x201] Any ideas how to get that group back ? thanks, Martin
