|I'm stumped by this problem. Recently we got some cabling done to connect a computer to the LAN. This computer gets an IP from the DHCP server, it can ping the remote gateway, it even resolves google.com to an IP when I try to ping google.com, but it can't ping it. I can't load any webpages in IE8, seems as if it hangs after resolving the name to an IP. Another computer on the same switch can't ping google.com either but can access webpages just fine. This computer is running XP on the other hand and is in the domain, while the non-working Vista machine is outside the domain. This shouldn't affect it's access to the internet though, as other computers (with XP) works just fine outside the domain even though they are connected to the VLAN the domain resides on.|
The network looks like this;
Computer<->Switch<->Switch<->ADSL with several VLAN outputs<->ISP<->Fiber<->HQ<->Servers. The Gateway, DHCP, Domain Controller and DNS-servers are all in HQ, DNS lookups go to HQ but then it connect straight to the internet through the ISP.
The reason PING doesn't work on the XP computer is that our network for some reason doesn't permit outgoing ping request, so it shouldn't be the problem. My theory is that there's some parameter in the Vista computers config that's not right, but as neither I nor my co-workers on the IT-department are familiar with Vista (all computers here are XP Pro machines, only computers that we didn't buy and setup come with Vista, usually through some grant or foundation that has donated the computer),
Our network i
