Local Connection Only

[TheB2B]

Since I don't see any post that matches my problem here goes.

Recently built out of spare parts and some new parts a Media Center PC. Loaded Vista Ultimate X64 on the box and have it hard wired to my network. Issue is limited connection on my network and no internet connection. All was working great until SP1 was installed. Since then I can not access the internet, ping my router or see my WHS or my wifes XP Pro laptop, but I can see and access my daughters laptop running Vista Home Premium and my laptop running Windows 7 RC1.

I have tired to disable IPv6 both through the proprieties on my nick and through the registry, no effect. Tried netsh winsock reset, no effect, also when I go into network settings network discovery is turned off, I enable it with no effect, next reboot it is off again. I saw a post about putting local services group in the administrators group, no effect.

I have a D-Link DI524 router my MC PC is showing up in the assigned IP tables, the IP that is returned when I do an ipconfig matches the one issued by the router.

As I stated before I had NO network connection issues until SP1 was installed. Is my only option to un-install or remove SP1, is that even possible?

Have you tried updating the network card's drivers on that PC?

Solved!!!! Sort of. :huh:

Here is what I have done. Off of the start menu I went in under network, then selected Network and Sharing Center, Manage Network Connections, right click on the network adapter, selected Properties, then selected Configure button under my network adapter. Then I selected the Advance tab and set the Priority and VLAN to Disabled.

Not real sure what this controls but I have full access to all devices on my local network and have an internet connection. In my view this is a work around at best. My solution was a bit of trail and error and intuition, like to say it was all brain power but I'm not that good. That is I worked all the possible solutions for the network stack, both what I know and what I learned on the net, so I moved onto the device itself and started doing varies trail and error methods until I found this solution.

Any thoughts, ideas or opinions on the solution to my problem or other was to fix this?

Glad to see you got it sorted and thanks for posting back a solution

Are you using an nForce motherboard? It seems these particular network interfaces cause problems for Vista and doesn't let it create a network map while priority & VLAN is enabled. Strange how it worked pre-SP1 and not after SP1, though.

You should be fine with this disabled, it's needed for larger networks and not for home networks. The VLAN segments the network virtually and the priority marks packets for priority over the network (I think, I could be wrong).

Uses VIA chipset, so that is not the issue. Talking with the previous MB owner, he donated this one as I upgraded his existing system, he to had an issue with vista and SP1. Installing SP2 now, see how that goes.

Notice several other posting with connection issues the description doesn't match my exactly but I wonder if the solution would apply?
