Microsoft Windows 2000 Registry Setting for Default TOS
DefaultTOS
In Windows 2000, it is possible to set the default value for the TOS field for packets that a host sent. Microsoft Windows Sockets applications can override this default value. By default, the DefaultTOS value is set to 0.
Changing the value of DefaultTOS is necessary only for testing, when all traffic from a host can be characterized in terms of a specific TOS, and TOS routing is supported by your routing infrastructure.
Key: HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters
Value type: REG_DWORD
Valid range: 0 - 255
Default: 0
Present by default: No
For example, to set all traffic from a host for routine precedence, minimum delay, and maximum reliability, set DefaultTOS to 20 (20 = 00010100).
