When there was a W2K DC in our network we were able to join the domain, but now that all DCs have been converted to W2K3 we're getting the following message when we try to use smbpasswd to join a new machine to the domain: Error connecting to xxxxxxxxx - NT_STATUS_ACCESS_DENIED Unable to join domain xxxxxxxxxxxxx I just noticed in the Samba-HOWTO-Collection, chapter 6, "Common Errors" section, these sentences under the "I Can't Join a Windows 2003 PDC" explanation: "Windows 2003 requires SMB signing. Client side SMB signing has been implemented in Samba-3.0." Is there any way for a 2.2.8a/2.2.12 client to join a domain whose domain controllers are all W2K3? -- Bruce Hobbs, CCP, CDP Engineered Software Office: 626-570-8028 Partner 856 N Monterey St Cell: 626-278-0273 Alhambra, CA 91801-1574 FAX: 208-474-0732
