Here’s a new Knowledge Base article we published. This one describes an issue where a PXE enabled Distribution Point will generate a large number of files under C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 for each PXE request that it services on the network.
=====
A PXE enabled Distribution Point will generate a number of files under C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 for each PXE request that it services on the network. This occurs whether the device sending the PXE request has a Task Sequence deployed to it or not. The generation of files will continue and may consume available hard disk space.
This occurs whenever a self-signed certificate is used for the Distribution Point (DP).
To work around this problem, request a CA issued certificate for the PXE enabled DP and specify the PFX file under the properties of the DP. Step-by-step instructions on how to do create the PFX file are available in the Deploying the Client Certificate for Distribution Points section of http://technet.microsoft.com/en-ca/library/230dfec0-bddb-4429-a5db-30020e881f1e#BKMK_clientdistributionpoint2008_cm2012.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
