How to fix SharePoint Foundation event id 7043

On Windows 2008 R2, you may receive the following error message multiple times in the application event log.
This can be ignored or you can fix with the quick change below.

Error details :

Event ID: 7043

Load control template file /_controltemplates/TaxonomyPicker.ascx failed: Could not load type 'Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker' from assembly 'Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.

To fix this :

1.Navigate to /14/TEMPLATE/ControlTemplates/TaxonomyPicker.ascx user control on each WFE server.
2.Open the user control in a text editor and locate the first line
3.Find the character string , and replace with a comma ‘,’ (without quotes).
4.Save the user control

I have had occasions where the fix has been implemented but still get the error. Then fell back to the line in the MS article below.
"This message should be treated as log noise and can be ignored."
