Hello,
May be somebody has experience how to make pings with TOS=160 (10100000) from Vista environment? Early for XP was necessary to make changes in winreg: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableUserTOSSetting = 0
For Vista I find this: http://forums.microsoft.com/unifiedcommunications/ShowPost.aspx?PostID=3886911&SiteID=57
But it is not working (as I see). Shortly what I want to do. I need to test how VoIP QoS is working in my MPLS provider line. So I measuring line delays and drops with pingplotter with DSCPTOS=160 (VoIP class) and DSCP/TOS=0 (best effort) at the same time. With XP it works fun. With Vista I see that all packets from me are sending with TOS=0.
Many thank for any information,
