I've narrowed down my issue to this: I remove all components from my local area connection, reboot, then add only the tcp/ip protocol component, with no client or service components. Now my Win2K can ping a Win98 PC, and it can ping me. BUT, after I reboot my 2K, 2K can still ping 98, but when 98 pings 2K, the 2k connection status window shows the packets being received, but it doesn't respond to the ping. What's going on?

Open a management console. Add IP Security Police Manager snap in to it. Check under the Secure Sever (Required Security) properties and make sure that you have All ICMP Traffic unchecked. Also check under Server (Request Security)for same. If it ischecked, your 2k machine will do as you described. After removing the check (if necessary) right click on all policies in the right pane of the console and select un-assign. It should be the first menu item. If it says Assign, do not select it. After making the necessary changes, go into your services and restart the IPSEC Policy Agent service. That should solve your issue.

Check the simple stuff first.

Check your IP configuration on both machines. Make sure that the subnet mask and Ip address is correct.

Have verified hub,cables,nics. Network works fine with ipx/spx. Both computers have no DHCP, no IPSEC, no WINS, netbios is enabled. IP addresses are 192.168.0.1 and ...100, subnet masks 255.255.255.0.

Tried suggested remedy and could not start the ipsec policy agent service.

The TCP/IP property window has an "Advanced" button that will open a second window. Go to the last tab and make sure you do not have the TCP/IP Filter enabled...

Lusu.
