Best Practices

  • Make sure that the correct number of threads are calculated.
    See Calculating the Number of Scan Processes in Symantec Mail Security for Microsoft Exchange 5.x and 6.x
  • Ensure that the correct exclusions are in place on the Server's Antivirus Program
    Administrators should add centralized exclusions to ensure that there is no chance that the AV product, which protects the server's file structure,  will scan materials that are in use by SMSMSE. The latest releases of Symantec Endpoint Protection (SEP) and Symantec Antivirus (SAV) should automatically detect MS Exchange and SMSMSE and set the correct exclusions. It is wise to create redundant exclusions to guarantee that there will be no interference. See Configuring exclusions when Symantec Mail Security for Microsoft Exchange and either Symantec Endpoint Protection or Symantec AntiVirus Corporate Edition are installed together
  • If Symantec Endpoint Protection or Symantec Antivirus is installed, Ensure SMSMSE's LiveUpdate is Configured Correctly
    For 32-bit Small Business Servers, SMSMSE's LiveUpdate should be disabled. SEP or SAV will automatically share definitions with SMSMSE. For 64-bit Small Business Servers, ensure that SMSMSE's LiveUpdate is enabled. For details, please see About Enabling LiveUpdate When Symantec Mail Security for Microsoft Exchange 6.0.9 and Symantec Endpoint Protection 11.x Are Installed on a 64-bit Exchange 2007 Server
  • Ensure that the SBS has ample resources
    The Small Business Server combines many important server roles on one computer (Active Directory Domain Controller, Exchange Server, MS SQL Server, SharePoint server, IIS, WSUS, and so on). Shortages of memory, processing power, and disk space can be common if the server is not configured and maintained well. A lack of resources has the potential to affect SMSMSE.
  • Use Microsoft's SBS Best Practices Analyzer to ensure the server is in good health
    Underlying issues such as low resources, old driver versions, and network trouble will have an effect on SMSMSE and MS Exchange. Microsoft has made a tool freely available which can analyze a Small Business Server and highlight any such issues. Symantec Technical Support recommends that these tools be run periodically and that server administrators act upon any errors, warnings, or recommendations.
