If we run nslookup then for passport.com

Server: ns1-isb.sdnpk.org
Address: 203.135.2.55

Non-authoritative answer:
passport.com nameserver = DNS4.CP.MSFT.NET
passport.com nameserver = DNS5.CP.MSFT.NET

Authoritative answers can be found from:
DNS4.CP.MSFT.NET internet address = 207.46.138.11
DNS5.CP.MSFT.NET internet address = 207.46.138.12

When I traceroute to DNS4.CP.MSFT.NET then

12 194.ATM4-0.GW3.SEA1.ALTER.NET (146.188.201.29) 348.981 ms * 347.277 ms
13 157.130.177.154 (157.130.177.154) 389.490 ms * *

or

> server DNS4.CP.MSFT.NET
Default Server: DNS4.CP.MSFT.NET
Address: 207.46.138.11

> lc1.law5.hotmail.passport.com
Server: DNS4.CP.MSFT.NET
Address: 207.46.138.11

*** DNS4.CP.MSFT.NET can't find lc1.law5.hotmail.passport.com: No response
from server

The above results show that DNS4.CP.MSFT.NET is down.

And when we type http://www.hotmail.com

The Netscape shows
Connect: Looking up host: lc2.law5.hotmail.passport.com

After some time netscape gives error Netscape is unable to locate the
server lc2.law5.hotmail.passport.com Please check the server name and try
again.

Any hints or any other facing this problem.
