Anybody else having a problem reaching (what appears to be) the sole Microsoft Product Activation server (wpa.one.microsoft.com)? $ ping wpa.one.microsoft.com PING wpa.one.microsoft.com (94.245.126.107): 56 data bytes 36 bytes from 213.199.189.41: Communication prohibited by filter I get this sourcing from our network, from AT&T 3G, and from ye residential DSL connection located in the greater Seattle area. They aren't simply source-filtering. Either that or they are source-filtering for 0.0.0.0/0. This is apparently the only server/IP they have set up to respond to these requests. wpa.one.microsoft.com resolves to that IP via every DNS server I've tried (so no round-robin A records), Microsoft products that need to activate over the internet only try to resolve that FQDN, and I've looked for others without success (wpa.two.microsoft.com isn't valid, for example). -- Nathan Anderson First Step Internet, LLC nathana@fsr.com
