Rich,
thank you very much for your answer.
Unfortunately, I'm not the DNS Admin (or I would say... thank you God!!!!).
I just wanted to find a easy way to solve an internal problem of my
department and ask the admins if was possibile to implement it.

Finally, I'd say that I will install a pair of DNS in my network and all
problems will disappear by one shoot.

Thank you,
