Exit and restart Windows Media Player.

Confirm that the Windows Media Player Network Sharing Service is started.

To start Windows Media Player Network Sharing Service
Click Start.

Right-click Computer, and then click Manage.

Expand Services and Applications, and then click Services.

If the Windows Media Player Network Sharing Service is not started, right-click it and click Start.

Restart your computer.

Confirm your user account is listed as an owner of the Windows Media Player database folder.

To confirm ownership of the database folder
Navigate to the <SystemDrive>:\Users\<UserName>\AppData\Local\Microsoft\Media Player folder. If you do not see this folder, you might need to turn on Show hidden files and folders.

To turn on Show hidden files and folders
In Windows Explorer, click Organize, and then click Folder and Search Options.

Click the View tab, and then select Show hidden files and folders.

Right-click the Media Player folder, and then click Properties.

Click the Security tab. If your account name is not listed, click Add and add it to the list of owners. You will need to be logged on as an administrator or a member of the Administrator's group to perform this step.

Confirm that you have ownership of the Windows Media Player Network Sharing Services registry subkey.

To confirm ownership of the registry subkey
Click Start.

Type regedit in the Start Search box, and then press ENTER.

Navigate to the HKEY_LOCAL_MACHINE\Software\Microsoft\MediaPlayer\Preferences\HME\[security ID] subkey. The name text of the security ID folder is long, composed of alphanumeric characters broken up with dashes.

Right-click the [security ID] folder, and then click Permissions.

Confirm your user account is listed as an owner of this subkey on the Security tab. If your account name is not listed, click Add and add it to the list of owners. You will need to be logged on as an administrator or a member of the Administrator's group to perform this step.
