End Point Protection client deployment not updating My Company Computers in SEPManager

I am using Symantec EPP manager (Small Business Edition) to deploy clients to computers in my organisation.  My Server is WinServer 2008R2 and the client computers are all Windows7.  The client is deployed successfully but the computer it is sent to does not show in the relevant computers folder in SEPManager.  The deployment report does not record the deployment as having occurred.

This feature has worked in the past.
