Can not ping some web site

[frank]

nslookup shows as following:

C:\>nslookup www.msn.com
Server: fremontbdc.pcs-ww.com
Address: 172.16.0.2

Non-authoritative answer:
Name: www.msn.com
Addresses: 207.68.171.245, 207.68.171.247,
207.68.172.234, 207.68.173.244
207.68.173.254, 207.68.171.244

Those clients are members of a domain and they are
pointing to the BDC for DNS (Now) I deleted the ISP DNS.
There is no "." (root) forward lookup zone except in
Cached Lookups.

I can not ping www.msn.com, www.aol.com but
www.yahoo.com. Any reason?

msn.com and aol.com are unpingable.

Hi Frank,

For security reasons many web sites block ICMP (ping) traffic. msn.com and
aol.com both block ICMP.

Thanks,
