Enable SCCM Distribution Point Maintenance Mode

Benoit LecoursSCCM1 Comment

SCCM Distribution point maintenance mode is a new feature available in SCCM 1902.

Following Microsoft documentation, you can enable maintenance mode when you’re installing software updates, or making hardware changes to the server.

During maintenance mode the SCCM distribution point can/can’t:

  • The site doesn’t distribute any content to it
  • Management points don’t return the location of this distribution point to clients
  • The distribution point properties are read-only. For example, you can’t change the certificate or add boundary groups
  • When you update the site, a distribution point in maintenance mode still updates
  • Any scheduled task, like content validation, still runs on the same schedule

Let’s try to enable maintenance mode on one of our lab SCCM distribution point :

  1. Can prestage content be added to the content library through extractcontent.exe while the server is in Maintenance mode?
