KB53344Just a quick FYI on a new Knowledge Base article we published today regarding the SLC for RMS. Windows Rights Management Services clusters that are based on Windows Server 2003 or Windows Server 2003 R2 use a root certificate (also called Server Licensor Certificate or SLC) that is issued by a service hosted by Microsoft. Originally, these certificates were issued with a one-year lifespan, which means that they must be renewed every year for the RMS cluster to continue working.

The Windows Server 2003 support lifecycle is set to expire in July 2015 so Microsoft changed the lifetime of SLCs that are issued for Windows Rights Management Services to 7150 days. This change was made to allow Windows Rights Management Services servers and clusters to continue to work after the service that is used to issue SLCs is decommissioned after the end of support of Windows Server 2003.

You can get all of the details here:
