Antivirus real-time protection can cause many problems on Configuration Manager site servers, site systems, and clients.

The following is a non-comprehensive list of possible symptoms:

  • Remote site system components are not installed. SiteComp.log, Distmgr.log, hman.log or other Configuration Manager log files may contain errors such as error 80070005.
  • The Configuration Manager client cannot be installed through Client Push.
  • Client inventory information is inaccurate, missing, or out-of-date.
  • Backlogs occur in the Install_Directory\Inboxes folders on Site Servers.
  • Backlogs occur in the Install_Directory\MP\Outboxes sub-folders on Management Points.
  • Software Center is not populated by deployed software on client systems, or does not start. Also, the CCMRepair.log file may contain errors that resemble the following:
    Database verification failed with result: 0x80004005 but DB: C:\Windows\CCM\filename.sdf could be opened, skipping DB repair.
  • Software that is deployed to clients cannot be installed.
  • Compliance data for software deployments is inaccurate.


We recommend that you add the following real-time protection exclusions to prevent these problems.

Do not scan Outgoing files on MPs

  • Most antivirus software has an option to scan files that are copied to a remote location (Outgoing files). This should be disabled on Management Points.
  • For Defender, the policy name is Configure monitoring for incoming and outgoing file and program activity and it should be set to Scan only incoming files.
    For more informaiton, see Enable and configure Windows Defender Antivirus always-on protection in Group Policy.
Process exclusions

Process Exclusions are necessary only if aggressive antivirus programs consider System Center Configuration Manager executables (.exe) to be high-risk processes.
