Error writing Encryption data to Web Services Configuration database (metabase). 0x8009000F=Object Already Exists.



CAUSE
This problem has been seen after the installation of PCAnywhere.



RESOLUTION
To resolve the problem, use these steps:  Remove IIS (by using Add/Remove Programs in Control Panel). Using Windows Explorer, change to the following directory:  If the Windows installation is an upgrade navigate to:

%windir%\Profiles\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys

 If the Windows installation is a new installation navigate to:

%system root%\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys

NOTE: Files in this directory are hidden. To view this folder and files, select the Show hidden files and folders option button in Folder Options.

  Copy all the files in the MachineKeys directory to another location (to back them up).</li> Delete all the files from the MachineKeys directory except the newest one (and not the backups!).NOTE: If you are unable to delete any of these files, try taking ownership of this directory. To do this, follow these steps:

<ol style="list-style-type: lower-alpha;"> Right-click the MachineKeys folder.</li> Click Properties.</li> Click the Security tab.</li> Click Advanced.</li> Click the Owner tab.</li> Highlight the Administrators group to change the owner.</li> Select Replace owner on subcontainers and objects.</li> Click OK.</li></ol> </li> Look for the following folder:

%systemroot%\system32\Microsoft\Crypto\RSA\MachineKeys

If this folder exists, repeat steps 3 and 4 on this folder.

</li> Restart the computer.</li> Install IIS (by using Add/Remove Programs in Control Panel).</li></ol>
