## Detailed Description

This section explains how to configure the Windows firewall available in Windows XP SP2 and later.

The Windows Firewall can be modified so applications can be added to the firewall's exception list.

The Windows Firewall was introduced in Windows XP SP2. Modifying the Windows Firewall requires administrator rights. On Windows XP the user running the application, which calls the DLL, is assumed to have administrator rights. On Windows Vista/7 the DLL will automatically call User Account Control (UAC) to obtain administrator rights.

Check out TT_Firewall_AddAppException() on how to add application executables to the Windows Firewall exception list.
