I tried for over a day to get Power Pack 3 via Microsoft Windows Update. I tried manually clicking on Update Now. The console would be unresponsive for several minutes, then provide me with a useless error message. At first, I figured maybe that the update server was busy. Then I decided to check my PeerGuardian2 log. It was blocking a LOT of outgoing requests to Savvis and to Limelight Networks, LLC.
Well, after a little digging, I figured it out. Savvis is actually TZO, who facilitates the *.myhphome.com dynamic DNS that the HP WHS uses.
And, Microsoft uses servers hosted by Limelight Networks for Windows Update. I never noticed the TZO problem, probably because my cable company hasn’t changed my IP address.
Here’s the IP addresses that I added to PeerGuardian2 to allow so that TZO and updates would work. Within moments, I was greeted with Windows Update updating.
Savvis – TZO.com
Limelight – Microsoft Update
