SCCM 1511 Computer Automatic Approval Not Working

Scenario

  • Clean SCCM 1511 install.

Problem

  • Noticed in the SCCM Admin Console that all the domain-connected clients were ‘waiting approval’ even though he Hierarchy Settings were correctly configured to automatically approve computers in trusted domains (right-click the Sites node under Site Configuration in the Administration workspace).

Root Cause

  • IIS on the Management Point did not have Windows Authentication enabled.

Solution

  • Enable Windows Authentication in IIS and restart all affected client agents.

Note:  Check all SCCM virtual directories have Windows Authentication enabled once enabled at server level.
