Windows 2000 Server Internet connection sharing not working

[david.cawkwell]

I have two computers

First computer is Windows 2000 Server and this connects to the internet
via broadband
with internet connection sharing enabled.

Second computer is Windows 2000 Pro and this connects to the internet
via computer
1 using this as a gateway.

This has been working without any problems. However it has now stopped
working.
Both computers can ping each other. Windows 2000 Server can access the
internet.
But Windows 2000 Pro cannot.

Now the strange thing. If I drop the internet connection. Disable the
connection sharing box.
Connect on again. Drop the connection again. Enable internet connection
sharing and connect to the internet. Windows 2000 Pro can now access
the internet. This has to be done each time I reboot the Windows 2000
Server machine.
What has gone wrong? How do I fix it?

Help please or it is a reinstall for the Windows 2000 Server machine.

Try:

1. Open a command prompt and run ipconfig /all on the server - note the IP
address of the DNS server on the broadband connection.

2. Manually configure TCP/IP on the Win2kPro machine:

IP address = 192.168.0.2
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.0.1
Primary DNS = IP addresss from #1.

The is no fault at the Window 2000 pro machine.
This is set correctly. The fault is at the Windows 2000 Server which
does the connecting to the internet. It is not routing the packets even
with ICS enabled.

How do you know packets are not being routed? Can the Pro machine ping
4.2.2.1? If not, does the Pro machine have a 192.168.0.x address with a
default gateway of 192.168.0.1?

If you confirm that packets are not being routed, try disabling ICS and
configuring RRAS NAT instead.

My configuration is exactly as you supplied in fact.
Server 192.168.0.1 and pro machine on 192.168.0.2

How do I configure RRAS NAT? What is it?
