What To Do

  1. Stop the following services:
    • 'Sophos MCS Agent'
    • 'Sophos MCS Client'
  2. Locate the 'Config' directory of MCS:
    • Windows XP/2003: 'C:\Documents and Settings\All Users\Application Data\Sophos\Management Communication System\Endpoint\Config\'.
    • Windows Vista+: C:\ProgramData\Sophos\Management Communication System\Endpoint\Config\'.
  3. Open 'Config.XML' in a text editor such as Notepad.

    Note: It is recommended you first take a backup of the file 'Config.XML' before committing any changes to the current file.

  4. To configure the logging changes for the 'Sophos MCS Client' service, within the 'McsClient' tags, create the following lines as appropriate:
    <logSize>4</logSize>
    <logCount>6</logCount>

    Note: The value for 'logSize' is the size in megabytes.

  5. To configure the same logging changes for the 'Sophos MCS Agent' service you may need to create, if it doesn't already exist, between the main 'Configuration' tags a new section called 'McsAgent' for example:
    <McsAgent>
      <logSize>4</logSize>
      <logCount>6</logCount>
    </McsAgent>
  6. Save 'Config.xml'.
  7. Start the following services:
    • Sophos MCS Agent'
    • 'Sophos MCS Client'
  8. To confirm changing the logging configuration has been successful, locate the log files of MCS to confirm the new rotation:​
    • Windows XP/2003: 'C:\Documents and Settings\All Users\Application Data\Sophos\Management Communication System\Endpoint\Logs\'.
    • Windows Vista+: C:\ProgramData\Sophos\Management Communication System\Endpoint\Logs\'.
