Now i have joined the cable from that XP LAN to another LAPTOP running vista

Now if set the LAN on VISTA to get ip automatically them internet don't work but if manually set the ip to

Then my internet works

But i want to join that LAN cable from XP to rouer so that i can use router to divide internet.

But i don't know how i can give static ipto router because i think somehow

that LAN on XP is not giving the IP address

Normally, ICS will configure the enabled LAN adapter automatically. You should not need to manually assign any IP configuration to the LAN adapter which has ICS enabled. It will also setup the DHCP server on that LAN adapter.

Perhaps by manually assigning the IP configuration on that adapter (if you did), you somehow disabled the DHCP server that would normally be set up automatically.

Connection/adapter (may not work with certain connections/adapters - e.g. pseudo adapters/devices) with the Internet connection that you want to share, the other adapters will be configured by Windows automatically in response. – user48838 Oct 31 '10 at 12:50
XP does not have a DHCP server that will run for ICS, a third party DHCP server may need to be added, or ZeroConfig enabled(does not route though) – Jimsmithkka Jan 7 '11 at 7:05
Actually, all versions of ICS includes basic DHCP server functionality (basically fixed to the net, if my memory serves me correctly) - no separate DHCP server needed when running an ICS network. – user48838 Jan 8 '11 at 8:03

You could use the DHCP server on the router to assign the IPs to other hosts on its LAN, and connect its WAN port to the XP pc. On the router you would need to set it as a Static IP (similar to the setting you needed to place on the VISTA machine)
