Fix Event Log Service Error 4201

[Original Post: Fix Event Log Service Error 4201 the Instance Name Passed Was Not Recognized]

Windows Event Log failed to start, and as a result, a couple of other services failed as well. Attempting to start the Windows Event Log service manually via the Services MMC resulted in error 4201. The complete error message is provided below:

Windows could not start the Windows Event Log service on Local Computer.

Error 4201: The instance name passed was not recognized as valid by a WMI data provider.

And the following errors popped up when opening the Event Viewer and Task Scheduler.

Event Log service is unavailable. Verify that the service is running.

Task Scheduler service is not available. Task Scheduler will attempt to reconnect to it.

The problem turned out to be the incorrect permissions for the C:\Windows\System32\LogFiles\WMI\RtBackup directory. The SYSTEM group needs full control permissions for the directory only when the Windows Event Log service would start.

Fixing the Permissions for RtBackup Folder in Windows 7 and Windows Vista

1. Start Windows in Safe mode.

2. Open the "C:\Windows\System32\LogFiles\WMI" folder.

3. Right-click on the RtBackup folder and choose Properties.

4. Click the Security tab, and click the Edit button.

5. Click Add, type SYSTEM and click [OK] button.

6. Enable "Full control" Permission to "Allow".

7. Click OK, and then click “Yes” button when asked for confirmation.

8. Restart Windows (in Normal mode), and verify if the Windows Event Service has started.

 

Unable to assign permissions for the RtBackup folder?

If you’re unable to assign permissions for the RtBackup folder, try taking ownership of the folder, and then repeat the steps 1-9 above.

Show sender’s e-mail address as a column in message view

Outlook only shows the Display Name of the person who has sent you the email. There is no built-in support for displaying e-mail address in Outlook. Using a custom form configuration file, you can display the sender’s e-mail address as a column in the message list.

1. First, download the viewsenderaddress.zip and extract viewsenderaddress.cfg file.

2. Place viewsenderaddress.cfg file in the the Forms’ language folder of the Office installation folder. The default location is similar to;
C:\Program Files\Microsoft Office\Office<version>\FORMS\<locale ID>

You’ll need to replace <version> and <locale ID> with the numbers matching your version and language of Outlook.

Examples;

• English version of Outlook 2007 on 32-bit Windows
  C:\Program Files\Microsoft Office\Office12\FORMS\1033
• English version of Outlook 2007 on 64-bit Windows
  C:\Program Files (x86)\Microsoft Office\Office12\FORMS\1033
• Korean version of Outlook 2007 on 64-bit Windows
  C:\Program Files (x86)\Microsoft Office\Office12\FORMS\1042
• Korean version of Outlook 2010 on 64-bit Windows
  C:\Program Files (x86)\Microsoft Office\Office14\FORMS\1042

3. After placing the cfg-file in its correct location, you still need to install it into Outlook. You can do this in the following way;

1. Open the Forms Manager dialog;
   • Outlook 2007 and previous
     Tools → Options… → Other → Advanced Options… → Custom Forms… → Manage Forms…
   • Outlook 2010
     File → Options → Advanced → Developers → Custom Forms… → Manage Forms…
2. In the “Forms Manager” dialog, press the “Install…” button.
3. Browse to the location where you’ve placed viewsenderaddress.cfg in the previous section of this guide.
4. Select the file and press “Open”.
5. A property window will open and press “OK” to confirm and close the dialog.
6. Press “Close” to close the Forms Manager dialog.

4. Now that the custom form configuration file has been installed, you can finally add the address column to your view;

1. Open the View Settings dialog;
   • Outlook 2003 and Outlook 2007
     View → Arrange By → Custom…
   • Outlook 2010
     View → Change View
2. Press the button called “Fields…” (Outlook 2007 and previous) or “Columns…” (Outlook 2010).
3. From the dropdown list called “Select available columns from” select “Forms…”
4. Here select “Sender’s Email Address” and press “Add →”
5. From the dropdown list called “Select available columns from” select “Sender’s Email Address”
6. Select “From E-mail Address” and press “Add →”
7. Use the Move Up and Move Down buttons to place it in the location you want.
