DNS page error with Microsoft

[RodrYguez]

Hi,

I have been scratching my head on it since the 12th of February. This
is really odd. New elements have occured, please read to the end.

I'm using Win XP Pro SP1.

I can't connect on any address beginning with www.microsoft.com at
all, but all other websites are ok.

When trying to access to www.microsoft.com (and all its derivated
forms), i get a DNS page error, but i can access support.microsoft.com
and every other websites. Also http://windowsupdate.microsoft.com
works but
http://www.microsoft.com/isapi/redir.dll?prd=ie&clcid=0x040c&pver=6.0&ar=ienews&os=N6
doesn't work.

Norton Antivirus, Trojan remover, AdAware, PestPatrol and Spybot (all
with the very last definitions) and even the Mydoom Worm Removal Tool
Version 3.0 made by Microsoft did not spot anything at all. No
infection is detected.

The HOSTS file is clean (only has 127.0.0.1 localhost), renaming it to
OLDHOSTS doesn't solve anything

Pinging www.microsoft.com resolves on www2.microsoft.akadns.net
207.46.144.188 or 207.46.245.214 and times out.

nslookup www.microsoft.com gives
name : www2.microsoft.akadns.net
Addresses: 207.46.144.222, 207.46.156.220, 207.46.156.252,
207.46.245.92, 207.46.245.156, 207.46.249.252, 207.46.250.222,
207.46.250.252
Aliases: www.microsoft.com, www.microsoft.akadns.net

Cache has been severally flushed without any success.
Internet Explorer Temporary Internet Files folder has been emptied as
well.

Registry settings under HKLM\Software\Microsoft\Internet Explorer
have been compared with another computer and are strictly the same.

Now i have tried the following test : if i use a *direct connection*
via A4proxy hearing 127.0.0.1 on port 8080, everything works ok.
So what is this damn huge mystery ?

The most odd thing is this : the connection to adresses beginning with
www.microsoft.com seems to work *randomly* depending on the opened
window of IE ! Let me explain : If you open, for example, 15 windows
of IE, and try to connect to www.microsoft.com within every one, one
window will always be able to connect (you could try connecting as
much as you want, it works) while all others won't.

Please help.

Thanks,
Rod

I have been experiencing this for over two weeks. Occasionally I can
get through but mostly not from my regular cable connection
(NTLworld.com). Investigation suggests that there is a router in the
MS area in Seattle which is not passing things on. I can always get
through on a different, dial up ISP which routes differently, and to
support. . . . where the route diverges just before the trouble.

I have asked through contacts for investigation (which brought it back
intermittently) - it looks as if it is a result of measures being taken
against the attacks of the MyDoom worm
