I have several cliets that are being updated with the lastest definiton file, but do not show up in the console. I have stopped the Symantec services on the server and re-started as per Symantec's advice, but still not all clients are displayed. I have also reset the realtime protection options so that all clients are forced to communicate with the parent server, but the result is still the same. Parent server is Windows NT4.0 Server SP6, Symantec 8.1 and clients are a mainly W2K.
