How can firewall settings on Windows XP affect the functionality of the Apache Monitor?

Firewall settings on Windows XP can block the Apache Monitor from communicating with the Apache server, causing it to not display the server status or allow for server management. To solve this issue, you can create an exception in the Windows XP firewall settings to allow the Apache Monitor to communicate with the Apache server.

// PHP code snippet to create a firewall exception for the Apache Monitor
$cmd = 'netsh firewall add allowedprogram "C:\Path\To\ApacheMonitor.exe" "Apache Monitor" ENABLE';
exec($cmd);
