Vista - Windows Vista / XP / ICS

I purchased a new HP DX2300 a week ago. I have spent countless hours (Days)
trying to setup ICS with no real success.

In my desperation I performed a restore on the Vista PC wiping out all
installs and configuration I did in the past week.

I installed all Windows Vista updates but NO other software of any kind. I
enabled ISC on the NIC that connects to the internet. All other
configuration was however Windows set it up in the install.

I rebooted the Vista PC and when it came up it could surf the internet. I
booted up another PC on my LAN (XP Pro) and It could surf the internet and
the LAN. The Vista PC could only see itself on the LAN and surf the internet.

I made NO changes and after 15 minutes (or so) things changed. At this
point, the Vista PC can view the LAN and the internet, the other PC can view
the LAN but not the internet.

I changed both Network Connections from Public to Private and turned off the
Vista Firewall. No change.

I rebooted the Vista PC. When it came up both PC’s could surf the internet
and the LAN. I booted another PC on my LAN. Now all 3 could surf the
internet and see each other on the LAN.

I waited 20 minutes and there were no changes. At this point it was getting
late and I need to go home. I shut down both PC’s on the LAN but rebooted
one of them. When it came up, it could not get to the internet but could see
the LAN. I checked the Vista PC and it also could not surf the internet.

The Vista PC was not rebooted nor had any configuration been changed. The
only change was the 1 PC on the LAN was rebooted and now neither PC can get
to the internet.

Someone PLEASE HELP! My new Vista PC is a pretty paper weight but I would
like to use it!

Now the feeling: Iam having vista work with my xp network and sharing
files/printer

I had the same nightmare that you are described, finally worked it out. My new Vista machine is the main pc connected to the cable modem input, other XP machines are connected through the hub. When I changed the TCP/IP settings on the XP machines to "obtain the IP address automatically", the XP machines were able to access the internet (with my file sharing still intact).

I ran all Vista updates then setup the ICS on the network card connected to the internet, now all is working.

ICS aka Internet connection shareing:
A) MS even admits it's not very stable but here you go:
Diagram of ICS:
Internet -Modem - Computer 1 -NIC with ICS -hub-Rest of the Computers

*Get it so that Computer 1 can surf the Internet without problems
Sounds like that you can get to happen
* Put any computer which in the diagam above are "Rest of Computers" on DHCP(aka Get IP Automagicly) for IP Address
and DNS
Afterware go Start->Run->cmd
then type ipconfig and press enter
you should get somthing like
IP address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway 192.168.1.1
->Test out the Internet
->If everyone can surf that is the end of ICS
Now File Sharing
Vista and XP do not look for other computers on the network the same way. So if your using the Vista Network Map and the XP computer is not showing up then you need an Update for XP.
go to technet.com (MS IT website) search is on the top right side
search for LLTD XP
or follow this link: Download details: Link Layer Topology Discovery (LLTD) Responder (KB922120)
Download and install the update.
IF the XP computer can not see the Vista computer make sure the Vista computer and XP computer are in the same workgroup:
Vista: Start-> Control Panel ->System
XP: Start -> Setting -> Control Panel -> System
Check that the workgroup name is the same and that the computer names are different.
-> If workgroup names are different make them the same and reboot
Otherwise:
Go to the Vista Computer
Start-> type in Network and Sharing Center and make sure file sharing is enabled.
