I have setup a small home network with a desktop running XP SP2, a Shuttle
Media Centre running Vista and network printer. Both PC can access the
printer and can transfer files across. Using the LAN portion of a D-Link ADSL
router for the interconnection but no ADSL connected. The XP PC has a 56k
Dial-up which I am trying to share with the Vista machine. I believe I have
done the set-up on both sides properly, IP addresses check out, workgroup
checks out, have firewalls up on both with Norton Anti-Virus on the XP end,
indeed can see a "residential gateway" on the Vista PC. Howver, when I try to
connect to the internet from the Vista PC, nothing happens on the XP PC (no
dial out). Even when I connect on the XP PC, no internet traffic flowing to
the Vista PC. Should this work? What am I missing?

Posting the results of both computer ipconfig /all here may help.

If I understand your setup, you're using the ADSL router as a network
switch to connect the two computers, not as a router. Disable the
router's DHCP server so that the Vista PC gets its TCP/IP setup from
the XP PC, then disable and enable Vista's LAN connection.

Check the TCP/IP configuration on the LAN connections. They should
be:

XP:

IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: none
DNS Server = none

Vista:

IP Address: 192.168.0.x (1x255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1

The Vista PC was looking for the router to connect it to the internet as
supposed to the XP machine. Default gateway was wrong! Talking to you from
the Vista machine now. Thanks for your help!!
