Check the below information: - Check an ip address of the system that you ping from whether it has a difference network id. - Check your system ist16 whether it configure to use IPSec or not.

This article[^] guide you on how to use IPSEC. After you read it you will know where is the place to set an IPSEC in your network.

I am assuming that you are talking about 2 machines on the same LAN? if so.. if you try to ping the IP address rather than name does it work? if not then it sounds like a DNS issue. Simon

Your system probably has Windows Firewall enabled and you haven't enabled the File and Printer Sharing exception. The default settings for XP SP2 is to turn ON the software firewall. The default setting for the firewall is to disable ICMP Echo request processing. Windows file sharing relies at some point on ICMP Echo (ping). Therefore enabling the File and Printer Sharing exception, or anything else that opens TCP port 445, enables ICMP Echo. If you have an Active Directory domain, you can use Group Policy to enable port 445 on all your workstations. I've done this to allow remote administration, but it's risky: some attacks spread using Windows file sharing. Stability. What an interesting concept. -- Chris Maunder
