outrageous DNS queries of isatap.mshome. from Residential Network.

[schilling <schilling2006 () GMAIL COM>]

Hi All,

In recent days, we have been seeing thousands of DNS queries of
isatap.mshome. from certain hosts in our Residential Network. They will just
keep asking the same questions over and over again, even non-domain is
returned.

Could somebody offer some clue on this?

Thanks.
