We have one client that is updating AV definitions according to the SEP client status screen and the client activity system log as accessed from SEPM, but the computer status log and home page in SEPM do not report the updated definitions. The cumputer actually has the 10/22/2009 definitions, but the SEPM home page and computer status log show 10/15/2009 definitions. I have already tried rebooting the machine several times. Client status in SEPM shows that the client is checking in to the server.
