Unidentified network Vista SP1 to XP on wired lan

> We have many issue with this settings:
>
> IP 192.168.0.1
> 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?

>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.
