1 - Run the "net stop http" command to stop W3SVC.
2 - Open regedit and add a subkey called ListenOnlyList as a REG_MULTI_SZ here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters
Then, in the multi-line string list (value) add which IPs you want to listen with on a separate line.
3 - Close regedit and then run "net start http" to restart W3SVC.
