SYMPTOMS
After you install the Zune software and you connect a Zune device to the computer, the Zune software does not recognize the device.

In the Navigation Pane of the Zune software, the device does not appear as connected. Also, in the Sync pane, you receive the following message:

Connect a Zune device

For more information about symptoms that you may experience when this issue occurs, see the &quot;More Information&quot; section.



CAUSE
In the Zune software version 1.2 and earlier, this issue may occur if the log file or the database in the %Systemroot%\System32\Catroot2 folder is corrupted. This issue can also occur if other errors exist in Cryptographic Services.

Note Typically, the &quot;systemroot&quot; path segment on a Windows XP-based computer represents &quot;C:\Windows.&quot;



THINGS TO TRY
 To resolve this issue, update to the current version of the Zune software. To do this, click Options, click Help, and then click Check for Updates. Follow the steps that appear on the screen to update the software. If the computer is not connected to the Internet, you can workaround this issue by rebuilding the Catroot2 folder. To rebuild the Catroot2 folder, follow these steps:  Click Start, click Run, type cmd, and then click OK. At the command prompt, type the following commands, and then press ENTER after each command:

net stop cryptsvc

ren %systemroot%\System32\Catroot2 oldcatroot2

net start cryptsvc

exit

 Remove all Tmp*.cat files from the following folder:

%systemroot%\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}

Note If no files that start with tmp exist in this folder, do not remove any other files. The .cat files in this folder are necessary for installing hotfixes and service packs. Wait approximately 10 minutes to make sure that Cryptsvc has enough time to re-create the database.</ol> </li></ol>
