Ian:

	For example: the server is telling to our customers that
www.microsoft.com is at 64.246.28.232, and not to the right address...
	That's what is happening.

Take a look at this another one:

# nslookup www.google.com.ar
Server:  zeus.multired.com.uy
Address:  206.99.52.140

Non-authoritative answer:
Name:    www.google.com
Address:  64.246.28.232
Aliases:  www.google.com.ar

	What do you think about this?

Saludos,
	Gustavo Castro Puig.
