Despite plentiful Linux & Windows experience, I've never yet managed to get a Linux box to work inside a Windows domain successfully.. So I am once again attempting this. :)
I've got a fairly virgin Ubuntu 7.0 install with the necessary Samba/Winbind installs. I'm following the guide at http://ubuntuforums.org/sh
Failed to set servicePrincipalNames. Please ensure that
the DNS domain of this server matches the AD domain,
Or rejoin with using Domain Admin credentials.
The smb, nmb and winbind daemons are all running and the domain is correct. The linux box has FQDN entry to the Windows server & itself in /etc/hosts, the primary DNS server is the Windows server & the order being DNS, HOSTS. As mentioned, this isn't the first time I've tackled the problem but I am getting more frustrated with each passing attempt. :(

OK, now I'm confused. I've tried added the FQDN of the linux box to the 127.0.1.1 address (I don't see how this fixes the problem) and the /etc/hostname contains only the machine name (no domain name). Now I get the error "Failed to join domain: Invalid credentials" from the "net ads join ..." command. The same credentials used with kinit work fine (and of course work on windows machines too).
Unfortunately, I cannot confirm either of the solutions, though both are certainly in the correct direction of a solution - I am therefore accepting both. Note, however, that I would not have expected the actual solution to pop up here: the DNS services on the Windows server were steadily failing & needed fixing first!

1: edit /etc/hosts
There should be a line with your hostname, you need to add your domain name to this: 127.0.1.1 hostname.DOMAIN.LOCAL hostname
2: ensure that /etc/hostname also has your hostname (not the domain) included there as well...
