I have had a lot of users who have just had a MS update and then found
their internet connection has gone. Symptoms are if you dial in on a broad band modem
you get bad username or password. You may then connect after several atempts
You cant then get any web pages you can ping a ip but not a name
and the ping has strange characters after it.
I havent been able to work out which update has done this yet its at the same time as IE7
These 2 files will fix the problem I would suggest you download them
now before you find you have the problem as if you have it you wont be
able to get back on the net.
