Xbox 360: PC Not Listed FIX

==THE PROBLEM==

For a long time, I’ve been successfully streaming video (using Windows Media Player) and audio (using Zune) to my Xbox 360. I just recently had a couple of updates to my PC: new CPU, new ram & a second video card – but no changes to the hard drive or windows. I did have to redo my windows activation since it relies on the CPU, but thats it! There were no problems and everything came up as usual. All the sudden, my xbox could not see the PC. However – the PC had no problem seeing the xbox!

I tried everything. I double checked that all services were running, automatic and started. I disabled sharing in WMP and re-enabled it. I even reinstalled ZUNE to recreate the sharing, but nothing. All uPNP, SSDP, Zune & WMP Network Sharing services were running with no errors.

==THE SOLUTION==

I assume by this point you’ve reset your router, your xbox and your PC multiple times hoping the problem will correct on its own. Now this isn’t a solution for everybody as different scenarios could have multiple problems, but it did work for me! I found on a lot of sites people talking about resetting the DRM entries on your XP machine. I figured the fix would be different on Vista since nobody was talking about it – and because its 2009, not 2005.

It’s called DRM – Digital Rights Management. You get the ‘PC Not Listed’ error code when the Windows Digital Rights Management (DRM) system on the computer is corrupted. The fix is fairly easy.

Make sure you are logged in as an administrator. Open up windows explorer by clicking on ‘Computer’ at your start menu. (you can also do this by going to start>run and type in userinit.exe – press enter)
In the top left corner, click on Organize and roll down to ‘Folder & Search Options’.
Click on the View tab and scroll down. Change the radio button about half way down to ‘Show Hidden Files and Folders’. Then, two checkboxes below that option is a checkbox that says ‘Hide protected operating system files (Recommended)’ and make sure it is UNCHECKED. Click Apply and Okay.
Back in your computer window, goto your C: drive (or wherever you installed Vista to) and you’ll see a folder called ProgramData. We are looking for this folder: c:\ProgramData\Microsoft\Windows\DRM
Rename the DRM folder to DRMBackup. If it gives you any errors, once again, check to make sure you are an administrator.
Go to this link in Internet Explorer (FF and Safari will NOT work): http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp?force=1
Choose the Upgrade button and let it do its magic. When it is completed, I recommend restarting the XBOX and the PC. Make sure you go through your Windows Media Player settings again to double check everything is being shared. Also, make sure the following services are started by going to start>run and typing in services.msc :

uPnP Device Host
SSDP Discovery
Windows Media Player Network Sharing Service
Zune Wireless Configuration Service (only if you stream your zune library to your xbox)

Last but not least – doublecheck that your Windows Firewall is not blocking anything important. Easiest way to do it is to disable the firewall completely and see if things work. If they do, you know there is an exception you need to allow.

Good luck!

P.S. – For More Information about this issue read the MS document: http://support.microsoft.com/kb/929642

P.S.S. – Another potential solution provided by Jason (thank you!) is to disable ICS. Easiest method is to go to control panel > network and internet > right click wireless or wired connection and choose properties. Click the sharing tab and clear the checkbox for ‘allow other network users to connect through this computers internet connection’.
