Event ID 4107 from Source CAPI 2 is logged under Windows 2008 R2 in the Application Log

21. September 2010

On some of our Windows 2008 R2 Servers we got the following event error:

Log Name: Application
Source: CAPI2
Event ID: 4107
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Failed extract of third-party root list from auto update cab at: < ( > with error: A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.

After a lot of searching i found this Microsoft-KB-Article which helped to fix the problem on our Servers:

The main steps are:
Open a cmd and enter: certutil -urlcache * delete

Open the following folders an delete the contents of the directorys – make a backup before you do that!! (Maybee not all of the folders exists on your system – than you have to do nothing for that folder)

%windir%System32configsystemprofileAppDataLocalLowMicrosoftCryptnetUrlCacheMetaDataDone – now the error message should be gone.

  1. Ive done all this and the error still persists.

    Ive done all this as well but it continues every hour, i have a feeling the server needs rebooting now.
