Jakub,
Sorry, I don't have 7 joined to our NT domain, so I don't know for sure. But from memory 7 doesn't have the same requirements or that you can make a registry change to allow it to join the domain.

Wow, thanks, that's reasonable.

What if I start windows 7 professional as domU and it fails joining with the exact same message. Windows 7 pro physical machines join perfectly.

Jakub,
I ran into problems with 2008 R2 and a NT Domain due to R2 absolutely requires kerebos to join the domain. There are posts all over the internet regarding this and no solution that I have found but to migrate your domain controller to at least 2000 or higher. (Either that or wait for Samba to catch up.)

One more funny thing:

If I just want to login on the NT domain server to browse the shared files, I can do that. I just type \\<hostname> in the explorer, I get a popup that asks me to login, i do, and i get the files. The only thing not working is joining the domain.

Hi!

DNS works nice.

If I logon onto the domU and ping the hostname of the NT domain server, the DNS resolves the server name and returns pings from 192.168.0.100 correctly.

The settings of the domU net card are OK. MAC address is the same as in the xen domU config, IP is 192.168.0.142 with correct netmask, route .1, dns .100, DNS search domain is OK.

Of course, the NT domain server name is different than the NT domain name. And the latter is not discoverable through DNS. I have read about propper setting of the DNS in NT domain by samba environment and this seems like a correct procedure. Or do you suggest otherwise? Physical hosts join the domain with no problem. This infrastructure is running this way since 2007.

Hi,

whats the settings of domU network card?

Seems to me like you are missing correct DNS server config there.
There should be IP of linux/samsa/LDAP server.

You can verify by ping "name of the samba server" if its resolved correctly.
