I spent many hours to figure out why I cannot register my developer device HTC HD7 to the App Hub:
An error occurred registering your phone. Please try again.
The help forum does not really help:
The phone registration service returned an unexpected ErrorCode value.
Check App Hub site for service alerts and/or retry after a few hours.
I have discovered that when the phone is connected to Zune, the internet connection in the telephone is broken, although it has wifi connected. So I became suspicious and finally started Wireshark. And indeed, Wireshark has answer to all your network questions. Zune bypasses proxy settings of the Windows 7 system. My setting say, it should neither use proxy nor try to discover one. I do this on purpose, because the default company proxy is too restrictive (Facebook blocking). But hey, this is not a forbidden site:
CONNECT developerservices.windowsphone.com:443 HTTP/1.0
HTTP/1.1 407 Proxy Authentication Required (Access is denied)
Via: 1.1 GFI WebMonitor Proxy
Of course, it bypasses settings, discovered a proxy but it is not able to authenticate – even though it offers NTLM!
In order to make any debugging even worse, it does some connections directly. So Zune will let you login to your account. It just uses different way how connect your phone to the internet – it will not let you even update the software if you are connected over proxy which requires authentication.
Registration of the company developer account has been a nightmare too, days of waiting. Support finally contacted us, but apparently things got fixed without their intervention.
Should I mention 10 steps of software update, which took 30 minutes, 3 automatic restarts and at the end told me it has more updates for me? How many of them were there waiting in the queue? Cancel.
