I recently migrated my company's Desktop Central server from a test environment to a production environment.  I am using build No:80014.  The problem I am experiencing is that when I scan my clients on the LAN for patches or inventory I get a message from all the SoM systems- "agent is not reachable."  I am sure that all the systems are not turned off, nor are they not logged onto the domain by a user.  I can install agents without issues from the DC server.  I can add or remove systems from the DC Server.  The Web Console is connecting okay.  I have allowed all inbound TCP ports 8020, 8027,8031, 8032, 8057, 8383, 8443, and 8444 open on the firewall where the DC server is located.

Anyone with an idea why my scans are not happening?
