I have a pretty weird thing going on. A computer was on the network until a few weeks ago since when it has been running stand-alone.
Now, I put it back onto a wired network. I can ping my router other computers on the network and also internet sites (ping google.com works fine). I can use windows explorer to explore other computers' shared files on the local network and open them.
Oddly, no internet apps seem to be able to go on the internet. I open internet explorer and it doesn't go to the homnepage. Likewise no mail, skype doesn't connect. Also, I have a network printer which can be configured with IE and which I can go to from other computers but not this one. Similarly, I can't go to the router.
Also, the network connection seems to be empty and using the wizard doesn't produce one.
I'm stumped on this one. Just wonder if anyone has any ideas?
