I'm so sorry to reply too late but I have lost the Internet connection.
I got to peform connection with the domain in the server.
The name of my server is SERVER1 and my test domain is called "empresa.local".
So, I have typed:
on the domain ingress box from the System Properties dialog. Logic that I got an error, but when I have deleted the "SERVER1." from the domain ingress box and has typed:
Windows have accept the ingress of the PC on the domain.
I don't why this has happen, but all the PCs get ingress to the domain with no problem now.
