Adjusting the ICMP Options
Making changes to the ICF's ICMP options is not to be undertaken lightly, especially if the network is a prime candidate for attack. Although each of the selections has a valid use, many are outdated and may not even be available from the Internet due to ISP regulations. However, on large networks that operate independently from the Internet, enabling ICMP may be necessary to assist network technicians with their duties. To enable ICMP options, observe the following instructions.
Right click on Network Neighborhood and click on Properties
Right click the connection using the ICF and select Properties
Click on the Advanced tab and choose Settings
Click on the ICMP tab
Check the options you wish to have enabled
Click OK, OK , and OK again, which will leave you at the Network Neighborhood window
