ICS no longer works

[Guest]

This started Friday - we have a basic workgroup all XP SP2 machines - one PC
has a dial up ISDN modem, that PC has ICS enabled on the dial up for the
modem, since friday, only the PC with the dial up connection can access the
internet - no other client workstation can access or force the dial up to
connect - as soon as you open IE on another PC it reports page not found.
Also, other PC's don't seem to be picking up valid IP addresses from the pc
configured with the Internet Connection Sharing. Any ideas of a fix /
resolution

Jeff,

Please start with "ipconfig /all" from the ICS host, and from a couple clients.

Disable ICS on the host computer, re-enable it, and see if the clients
can connect.

Have you added a firewall program to the host recently? Some
firewalls are incompatible with ICS.

Hello there, on the workstation setup with ICS, ipconfig /all reports:
ip address - 192.168.0.1
subnet mask - 255.255.255.0

On all the other workstations:
ipaddress: 169.xxx.xxx.xxx

I've run the network troubleshooter, re-run the ICS wizard on the host pc,
then rebooted the client pc's - still reporting the same issue.

Jeff,

A complete and unedited copy of "ipconfig /all" for both computers might provide
more diagnostic ability.

That aside, with the ICS host showing an IP address of 192.168.0.1, and the
client showing 169.254.x.x, it is quite likely that either:
1) There is a physical problem between the host and client.
2) The ICS host is not running the WF/ICS service.

Hello,

I tried disabling ICS, rebooting, then re-enabling, the station with ICS
configured can access the internet with no issues or problems, clients still
don't obtain a valid IP address. I checked all clients are within the same
workgroup.

Checked the list of Services running on the host PC: the "Internet
Connection Firewall / Internet Connection Sharing" service is not even listed
as a service, but the dial up isdn connection shows as firewalled and the
options show it has ICS enabled.

There have been no checnges to the host PC recently, client PC's have been
updated via Windows Update, the host PC was as up to date as possible, so
unless a user has changed settings / options and not told anyone I'm at a
loss now as to what has caused this issue
