Enmanuel,
The problem was solved after they stopped and restarted SQL Server.
Something was happening, I don't know what it was, and also it's not normal to stop and start a SQL in production environment.
I think someone changed some SQL Server settings.
The most important is it works now!

Thanks!

Peter
