Howdy All, I am trying to add more winxp machines to an existing domain and I think I must have broken something. The story goes, I discovered that it is a bad idea to have the computername and username the same, so I thought I would change the computername on one machine ( at a time ). However after trying with the first machine ( and failing ) I gave up thinking I would come back to this issue. However,when I try to add ANY new machine to the domain with smbpasswd -a -m newmachinename I get failed to initialise SAM_ACCOUNT for user newmachinename$ failed tomodify password entry for user newmachinename$ This tells me that it recognises the account as a machine trust account, but the database is bust. HOW DO I FIX IT ( or if all else fails can I remove the smbpasswd file and simply add all of the accounts again ) ?? The latter is not my favourite option but I will do it to get things going. The second and more important question is WHAT DID I DO to break it. I really dont want to have to go through this regularly.AND is there some backup of the database ( or can I create one on a dynamic system ) and if so what files should I be backing up. Thanks in advance. Regards Greg -- System Manager RGTechnologies Pty Ltd 606 Skipton Street Ballarat 3350 613 53363603 0417 511 731 andrews@rgt.com.au
