I relatively recently implemented Samba 3.026a (Solaris PDC) I then moved the PDC role to another machine. On the new pdc I 1st grabbed the domain SID newpdc# net rpc getsid -S oldpdc Storing SID ------------------for Domain MYDOMAIN in secrets.tdb newpdc# and then updated the smb.conf file on each machine to convert the PDC to member server and vice versa. If I ran the "net getlocalsid" command on the old PDC prior to the migration, it would return the SID for the domain. oldpdc # net getlocalsid MYDOMAIN SID for domain MYDOMAIN is: S-1----------------------99 oldpdc# If I run "get getlocalsid" on the new PDC I get newpdc# net getlocalsid [2007/11/01 14:52:55, 0] utils/net.c:net_getlocalsid(622) Can't fetch domain SID for name: NEWPDC newpdc # However explicity specifying the domain name seems OK newpdc# net getlocalsid MYDOMAIN SID for domain MYDOMAIN is: S-1----------------------99 As far as I can tell everything is working OK. But did I mis a step in the change over? Thanks
