Normally, on a computer running Windows NT 4.0, you cannot disable the source routing feature for the TCP/IP protocol. By using this tweak it is possible to disable it.
Open your registry and find the key below.
Create a new DWORD value named 'DisableIPSourceRouting' and set the value to either '1' to disable source routing, or '0' to enable source routing.
Exit the registry and reboot.
Note: You must have Windows NT Service Pack 5 or greater intalled for this setting to work.

Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Value Name: DisableIPSourceRouting
Data Type: REG_DWORD
Data: '0' or '1'
