Problem after Vista Service Pack 1

[Alan]

Hi,

I just did a brand new Vista Business install on my new computer, and I
downloaded the SP1. Before the SP1 update, I have no problem with browsing
all the websites, everything seems to work as usual. After the SP1 update,
it looks like I am having problem with network connection. Under Network and
Sharing Center, I saw a X my network to the internet. I have a hard time
browsing the net, whenever I type some site (Ex. www.nbc.com), it will jump
to microsoft live search. I have no problem with my network, other pc just
work fine. I just wonder if anyone experience this and know if this is the
problem of the SP1 update.

Sorry, I think I know what the problem is. My network has 2 gateway (Ex.
192.168.20.41 and 192.168.20.222), I ordered on my DHCP server option to set
..41 first and .222 the second. Everything works fine with all the XP clients
and Vista before SP1. I did ipconfig /all, and it shows .41 as the first
gateway. I ping some host name and it returned as host unreachable from
192.168.20.222, that's how I know it is not using the first gateway.

My question is why isn't vista using the gateway in the order it was
obtained? Can I do something in the network connection, so that it follows
this rule. What has changed in SP1 that changes this behavior?
