    I am Writing in to try to figure out why the "SSDP Discovery Service" is constantly flooding my network with requests.... so much so I think that it is cause resolution errors... with DNS servers on my network here is the copy text from my Outpost firewall after 3 hours usage.


    SVCHOST.EXE    UDPv6    ff02::c    1900    "SSDP Discovery Service" and "UPnP device Host" services    290 121 216    0

    There is no other computers networked to this one however I do use wifi.  I checked to see that options to "automatically switch to a better connection" was off it was. I try to disable the uPnP and SSDP Service and lost all connectivity as well. But it seems since I the last couple of months with Vista then a totally clean install of Win7 I have had about 30-40% resolution errors only with this computer finding websites. My latency for such games went from a typical 62-74ms to a 594-694ms while logging in. If there is no way to disable this constant flooding of broadcasts I might return windows and switch a different platform. Finally I never mention I am not using this in network sharing fashion such as files, being able to log into other pc's just as a wireless PC.  
     
    Finally off subject After the clean install i continue to try to pull files and delete the Windows.old folder it will not let me. I am the Admin of this computer and when I try to run Explorer as with Admin Credentials it asks for my password and does not accept the Password I gave with my credentials. Some help would be greatly accept. Finally in the 5 minutes it took me to write this post Bytes Sent from the SSDP Service count is 10mb in 5 minutes. THIS UNACCEPTABLE NO MATTER WHAT THE REASON .

    SVCHOST.EXE    UDPv6    ff02::c    1900    "SSDP Discovery Service" and "UPnP device Host" services    300 765 696    0

    The SSDP I think is being used to broadcast availability for IPv6 Homegroup. Disable homegroup and disable IPv6 as you likely don't need this for quite some time. This stopped the broadcast or more so multicast traffic that I was getting.

    As far as the Windows.old files prompting you for a password in which it doesn't accept, be sure you go to Control Panel>Administrative Tools>Local Users and Groups and make sure that there is not one account you are logged in as (maybe your name), and another just called Administrator which you would not be logged into this moment. Try logging in as this Administrator account versus just an account that is an admin.

    No matter which way you put it, we need an OS that supports our new software, new protocols, new hardware...and not many other platforms can do that, stick with it...you'll find peace of mind when you get through the new. :)
