I have deployed the SCCM 2012 NAP Agent on a few clients and it goes in and out of compliance approx every 2 min.
So its compliant for 2 min then uncompliant for about 30 sec then compliant again. If I uninstall the single software update I have enforced with NAP on SCCM the update is remediated properly by NAP/SCCM but the cycling in and out of compliance continues.
I did have the agent in sccm set to 2 min evaluation cycle for testing purposes but have now reverted it back to one day. The Health Validation Point is set to 26hrs.
