Hi List I get the same SID for local-domain and domain on my PDC. See this output: admin1:/data/profiles# net getlocalsid SID for domain ADMIN1 is: S-1-5-21-3215027423-1217727205-3511383706 admin1:/data/profiles# net rpc info Domain Name: EXEDIO Domain SID: S-1-5-21-3215027423-1217727205-3511383706 Sequence number: 1067424880 Num users: 20 Num domain groups: 4 Num local groups: 0 should the 2 SIDs be the same also on BDCs and Domain Member Servers? and how do i make them equal? at the moment the servers have a different sid by "net getlocalsid". and this sid differs also from the machine SID in LDAP any help is appreciated. cu tommi -- Thomas Otto Dipl.
