strange DNS behavior over the last 2 days

["steve baker" <stephenbbaker () hotmail com>]

For some odd reason, periodically our clients will visit a site, only to 
have a blank page appear as if the site loaded.

Nslookup resolves the correct IP address, but ping returns 64.251.66.2 for 
every address that has this problem.  There are NO hosts files on these 
machines and regardless of which DNS server we point them to, the same 
problem occurs.

The problem occurs intermittently as well, which makes it even harder to pin 
down.  Some sites previously affected will be accessible and new sites not 
affected suddenly have the same problem - but they eventually clear up in 
just about 10 minutes.

Very strange.  Has anyone heard or seen this before on a network running 
windows nt 4 DNS server with nt/2000 clients?
