I think I've got it fixed - time will tell.
22.214.171.124 SSDP NOTIFY - the only traffic on the her box - over & over & over.....
1. Start Registry Editor (Regedt32.exe).
2. Locate and click the following key in the registry:
3. On the Edit menu, click Add Value, and then add the following registry value:
Value name: UPnPMode
Data type: REG_DWORD
Value data: 2 ---- although another page said set to 0 so I did
4. Quit Registry Editor.
at least it "seems" to be a whole lot better.
Thanks for the wireshark - it did the trick.
