Hi Pam,
If this is enabled, try disabling it and enabling it again.

How to Enable Internet Connection Sharing on a Network Connection in Windows
The information in this article applies to:
  a.. Microsoft Windows 2000 Server
  b.. Microsoft Windows 2000 Advanced Server
  c.. Microsoft Windows 2000 Professional
This article was previously published under Q237254
For a Microsoft Windows XP version of this article, see 314066.

With the Internet Connection Sharing (ICS) feature of network and dial-up
connections, you can use Windows to connect your home network or small office
network to the Internet. For example, you may have a home network that connects
to the Internet by using a dial-up connection. By enabling ICS on the computer
that uses the dial-up connection, you are providing network address translation,
addressing, and name resolution services for all computers on your home network.
To enable ICS on a network connection:
  1.. In Control Panel, double-click Network and Dial-Up Connections.
  2.. Right-click the connection you want to share, and then click Properties.
  3.. Click the Sharing tab, and then click to select the Enable Internet
Connection Sharing for this connection check box.
  4.. If the connection you are sharing is a Dial-up connection and you want the
connection to dial automatically when another computer on your home network
attempts to use external resources, click to select the Enable on-demand dialing
check box.
NOTE: To enable ICS in Windows, you must have administrative rights.

IMPORTANT: You should not use this feature on a computer running DNS server or
DHCP server or a Windows domain controller. When you enable ICS, the network
adapter connected to the home or small office network is given a new static IP
address configuration. Existing TCP/IP connections on the CS computer are lost
and need to be re-established.
Configuration and Usage Issues
The ICS feature is intended for use in a small office or home office in which
the network configuration and the Internet connection are managed by the
Windows-based computer on which the shared connection resides. It is assumed
that on its network, this computer is the only Internet connection, is the only
gateway to the Internet, and that it sets up all internal network addresses.

You cannot modify the default network configuration after enabling ICS. This
includes items such as the range of private IP addresses that are handed out
(DHCP allocator), enabling or disabling DNS, configuring a range of public IP
addresses, or configuring inbound mappings.

If your home office users need to gain access to a corporate network that is
connected to the Internet by a tunnel server from a ICS network, they need to
create a virtual private network (VPN) connection to tunnel from the computer on
the ICS network to the corporate tunnel server on the Internet. The VPN
connection is authenticated and secure, and creating the tunneled connection
allocates proper IP addresses, DNS server addresses, and WINS server addresses
for the corporate network.
