I use Internet connection sharing of WinXP SP2.
Same problem here all the PCs on my network that have winxp have internet but the pc that i installed the Vista beta 2 has no internet but the worst is that i can ping internet websites!
I disabled firewall etc.
ping www.google.com for example but no page can be loaded in IE.
so i have internet communication but no webpages, i even tried other browsers but nothing.
I noticed on strange thing that in the network centre i find an unknown residential gateway with the ip of the pc with ICS.
I also noticed error in the Network setup WIZARD.
