Windows 8, Store and MS TMG Proxy - Can't install apps

$

0

Hi All,

Hoping for some information/assistance. Currently testing Windows 8 Ent x64 in our Domain Environment. All works well for the built in apps and certainly looks promising. Hoping to get quite a few Surface or other W8 Tablets in the organisation if I can fix this final issue.

I currently cannot install any Apps via the App Store through or Microsoft TMG 2010 SP2 product. I can change rules on the TMG to help make this work if necessary.

This is the message I am currently experiencing when I attempt to install an App:

"Your purchase couldn't be completed. Something happened and your purchase can't be completed"

I hit Try Again and immediately I get the same message. I have traced it to WindowsUpdate.log in the Windows dir which shows:

The key line here being: Last auth Schemes used: 'None'

Which gives the error: hr=0x8024401c - Authentication error?

This leads me to the TMG live Proxy log. Which shows all as Allowed Connection but the HTTP Status Code is 407 Proxy Authentication Required:

Status: 407 Proxy Authentication Required
Rule: Allow Unfiltered Internet
Source: Internal (172.16.2.23:64163)
Destination: External (172.23.0.10:443)
Request: fe1.ws.microsoft.com:443
Filter information: Req ID: 0f74228b; Compression: client=No, server=No, compress rate=0% decompress rate=0%
Protocol: SSL-tunnel

User: anonymous

Is there a rule that needs to be added to the TMG/Web Access Policy to allow Unauthenticated traffic to certain domains or is there something on Windows 8 (without having to install anything as this is not an easy solution to roll out to RT tablets for example)

Many Thanks for any assistance. I may crosspost this to the Windows 8 forum too.

Regards,

Dan.
