Certificate disappears after a few hours?


I am running NPS for wireless certificate authentication on two 2008 domain controllers.

Default certificates on these servers are based on the templates "Domain Controller Authentication" and "Directory Email Replication".

However, none of these are accepted as EAP certificate in the NPS policy, but if I add the "Domain Controller" certificate everything works as expected.

My problem is that this new certificate vanishes after a few hours, and I have to enroll a new to enable user access to the wireless network.

What can cause this behaviour?
