SCOM - Windows 2000 agents not loading certificate

Problem:
=======
Customer had several Windows 2000 agents configured to use certificates to authenticate with OpsMgr (they are in a separate forest or workgroup).

Cause:
=====
we did not had the updated version of crypt32.dll causing the certificates error

Solution:
========

This problem will happen if crypt32.dll (on the win2k agent) is earlier than version 5.131.2195.6824.

Check the version of the crypt32.dll on the Windows 2000 server, if it is 5.131.2195.6661 change this to 5.131.2195.6926 from the Update Rollup 1 for Windows 2000 SP4 (KB891861)
