Dear All, I config samba-2.2.1a-4 in Red Hat 7.1 as a PDC. I successfully add Windows XP as a client but I have to patch "Xpsignorseal.reg". On Windows 2000, it already display "Welcome to domain...". I restart windows and logon to my domain. Windows show this error message: "The system cannot log you on to this domain because the system's computer account in its primary domain is missing or the password on that account is incorrect." But I already test this account. I already set "encrypt passwords = yes". Would you please tell me how to solve this problem? Thanks, Theewara -------------- next part -------------- HTML attachment scrubbed and removed
