SEPM defintions not updating itself - other clients updating

Hi all,

I have a Windows 2012 SEPM server running verision 14.0.1904.0000 - it seems to be managing all the clients fine, except itself.  The virus definitions are stuck at 12/31/16, but proactive and network defintions are current (Jan24/17 and Feb01/17).  Can someone tell me how to get rid of the corrupt virus definitions for the server - but not the ones it pushes to all the other clients - I only want to "refresh" the local SEPM server virus defs.  I found documentation for SEP 12, and Windows 2008 R2 servers - but not my set up.

Hope that makes sense...

Thanks,

Eric
