Down the road
Ive suddenly lost the ability to connect to any Microsoft website?!?
Therefore, I cannot run Windows update etc. and a whole host of other sites (MSN, Microsoft.com etc.) are all inaccessible.
All other sites are fine (hence my posting this message), its just MS sites that will not work.

If I try to ping Microsoft.com I get the following:

Code: 
Pinging www.microsoft.com [207.46.19.30] with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 207.46.19.30:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

and if I try a traceroute I get this:

Code: 
Tracing route to www.microsoft.com [207.46.19.30]
over a maximum of 30 hops:

I cannot ping or connect by any IP address for Microsoft.

I am currently on a 2MB ADSL connection. My IP and DNS are assigned dynamically upon connection.

Any ideas on the cause of the problem and how I can resolve it?

Thanks
 
Looks like a routing screwup somewhere in BT. Like csmager said, the lack of a ping means nowt, but your trace doesn't even get as far as the US. Mine on the other hand gets at least as far as Seattle before bumming out:

Code: 
gateway#traceroute www.microsoft.com

Translating "www.microsoft.com"...domain server (212.23.3.100) [OK]

Type escape sequence to abort.

You'll have to give BT a call. When they start asking you to reboot your PC/scan for viruses/stand on your head/whatever, tell them that you've done a traceroute which doesn't even reach the US and you can also give them mine so they have something to compare it to.
 
Figured it out.
The MTU was set too large on my ADSL Router. Set it to a smaller value and its working now (after setting it in the registry too!).

Thanks fellas :)
 
Dont really see how that could solve it as your MTU sizes mean nothing after the first hop and they're resized according to the link to the next hop.

But all in all, it works so meh.
