Endpoint Protection

I have just completed the exercise to migrate sepm to Windows Server 2008 R2 and upgraded from version 12 to 14. After upgrading the sepm and deployed the client package 14.0.3752.1000, most of the clients virus definition not updated since then and some of the clients virus definition shows "Not available". I have no idea what has gone wrong. Please advise some fixes that I can resolve this problem, thank you.

Have you looked at an affected client? Have you enabled sylink logging on the client so you can see the communication between client/SEPM? Download and run SymDiag on the endpoint as well to do additional error checking.

attached is one of the client's results from symdiag.

SymDiag indicates the client has a corrupt definition set:
