Installing and Configuring Fiddler
Fiddler is a tool used for monitoring internet traffic. We can use it to gather more information on errors you may be seeing. Visit www.fiddlertool.com to install.
Once you’ve installed it, run it and then open Internet Explorer at a favorite web site. You should see a list of connections in fiddler similar to the following:
http://cid-390f118edc5ea612.skydrive.live.com/self.aspx/Public/fiddler1.jpg
The next step is to configure Fiddler to also decode SSL traffic.
In Fiddler, select Tools, Options and check the boxes:
· Capture HTTPS CONNECTs
· Decrypt HTTPS traffic
· Ignore server certificate errors
Note the highlighted areas in the box below:

Next you need to configure Windows to trust the Fiddler Root Certificate.
Open a SSL site in IE like https://www.microsoft.com and you should see a page like the one below:
http://cid-390f118edc5ea612.skydrive.live.com/self.aspx/Public/fiddler3.jpg
Leave this page open and next start the certificate manager, select Start, Run and type “certmgr.msc”
You’ll see a window similar to the one below:
http://cid-390f118edc5ea612.skydrive.live.com/self.aspx/Public/fiddler4.jpg
Find under Personal Certificates the “DO_NOT_TRUST_FiddlerRoot” certificate and drag this to the Trusted Root -> Certificates folder.
You now have fiddler setup to monitor HTTP and HTTPs connections.

This indicates that HTTPS connection monitoring is working. If you double click on one of the entries above with the HTTPS you can then inspect the contents of the web exchange.
Saving Fiddler Traces
1. Close all programs
2. Start fiddler
3. Start Zune and repeat the steps that bring you to the error, after the error appears close Zune
4. Go back to fiddler and find the line where the url is usage/upload
5. Right click on that line and select File, Save, Sessions, in Archive/Zip
6. Specify a location for the file (e.g. Desktop) and a filename (e.g. “Download failed”, “can’t purchase”, etc)
7. If it prompts you save all sessions select Yes
At this point, we should have enough info, send me a Private Message notifying me that you’ve completed this and have the Fiddler trace, and I’ll let you know where to go from there.
Thanks for your cooperation!
