Unidentified network Vista SP1 to XP on wired lan

Hello
Before Installing Vista Ultimate X64 SP1 my wired (crossover cable)lan
was working fine. Network identified as private Home network. Settings
below with static IP

Vista Ultimate x64

IP 192.168.0.1
Subnet mask 255.255.255.0
Default gateway 192.168.0.1
Default Dns 192.168.0.1

Win XP

IP 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.1
Default Dns 192.168.0.1

After I install SP1 setting as follows

Vista Ultimate x64

IP 192.168.0.1
Subnet mask 255.255.255.0
Default gateway
Default Dns 192.168.0.1

Win XP

IP 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.1
Default Dns 192.168.0.1

Vista computer is connected to the internet with dial up modem. Vista
and XP connected with crossover cable no router. The problem is after
SP1 I can't set the default gateway on vista. Every time I type the
setting 192.168.0.1 and close the network center even after reboot the
gateway setting is cleared. As a result the network is Unidentified
network Public I can chance the public to private but after reboot it is
again public. I can however open XP in the network and share files with
XP. I have already disable IPv6 with no luck.

Any help will be appreciated.

We have many issue with this settings:

Subnet mask 255.255.255.0
Default gateway 192.168.0.1
Default Dns 192.168.0.1

The Vista can't be DNS. Why does the Default gateway points to 192.168.0.1?
Can you ping each other by name?

Yes I can ping by name.The default gateway point to 192.168.0.1 because
when you enable ICS the gateway is chance to 192.168.0.1.ICS is not
enable at this moment. The problem is that the gateway setting will not
stay.

Vista's Local Area Connection doesn't connect to the Internet, so it
doesn't need default gateway or DNS server settings.

A computer can't be its own default gateway or DNS server, so your
previous settings specifying 192.168.0.1 weren't technically valid.

When you connect to your dial-up ISP, Vista's dial-up connection will
get default gateway and DNS server settings from your ISP.

The default gateway and DNS server settings don't determine whether a
network is public or private. Something else is causing the network
to be identified as public. I've seen Vista temporarily mis-identify
a network as public for a few minutes after the computer starts, then
correctly identify it as private.

Getting exactly the same results. Have 2 Vista machines. One connected
to a cable modem as the host which is Vista Home Premium, ICS has been
set on the modem. The 2nd PC has Vista Ultimate and connects to the host
computer through a hub. Initially the host IP was set to 192.168.0.1
subnet of 255.255.255.0 and the gateway was set to 192.168.0.1 which is
what I was told to do to get a Home network and not an unidentified
network which occured when the gateway was left out. The client was set
to 192.168.0.50 subnet mask of 255.255.255.0 and a gateway of
192.168.0.1. After installing SP1 on both machines, the 2nd client
machine cannot get to all websites. It can get to some but not others!
Checked the host machine where the ICS has been set and noticed the
network is now an unidentified public network. The IP address of the LAN
is now 192.168.0.1 with a subnet of 255.255.255.0 and no gateway. Tried
to put the gateway in as 192.168.0.1 the setting does not stay. I know
the websites are all ok as when I go to the host machine you can connect
to the site. However on the client you cannot. Any ideas please?

I don't know about a hub because I don't use one but what I have figure
out is with ICS The IP address for the client must be set to be obtain
IP automatically. The host get a static IP of 192.168.0.1 from ICS. I am
no expert but I hope this help.

It's usually best to configure an ICS client to obtain an IP address
automatically. But it isn't necessary. You can make these manual IP
settings on an ICS client:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1 or your ISP's DNS server
