Step 16 - Change Timeout on Certification Path Validation Settings
Applies To: Windows Server 2008, Windows Server 2008 R2
This step explains how to change the default path validation cumulative retrieval timeout from 20 seconds to 2 seconds. This is required because the servers do not have access to the internet. If this gpo setting is not changed then the AD RMS Bulk Protection Tool will fail when attempting to activate the FCI server. This is only required because the server does not have internet access.
