[Samba] Windows XP issues

[Franco Suarez]

HI to all!

My Name is Juan Franco. I'm from Argentina, I work in a big gubernamental
organization and we are migrating our deprecated (smb3 + Ldap + NT4) to
Samba 4 AD DC:

But I have some issues with newer versions. if I install a version newer to
4.9.x. Windows XP can't join the domain.

The error message is ".. No *more connections can* be *made* to this remote
computer at this time", but with older versions i dont have the issue.

Any ideas?
Greetings!
