Win7 Cannot connect to ms sites, including EPG

[drgreenway]

Hi, I've stumbled across an odd situation, none of my computers will connect to microsoft.com, and my HTPC will not download the EPG, it says I have no internet connection because the server could not be contacted.

msn.com, msdn, windows update, technet.microsoft.com are all working.

I guess it's something to do with my router as all computers are affected, it's a BT Voyager 2100 with the latest firmware (but that was from 2007).

Is this a common problem? All the rest of the web is working fine, but it's just this. BTW, on initial setup of my HTPC it set up and downloaded the guide fine.

Weird. Any suggestions?
Thanks,
Mike

I had tried yesterday to change the MTU settings of the router to a lower number (was default set at 1400) as suggested by a few sites. I changed to my SKY router which worked no problem, the MTU was set at 1500. I went back to the Voyager and tried 1500 there, and hey presto!

As I say - Weird.
