computer in sccm shows question mark icon
a computer object icon in sccm console shows question mark (?). one client has this issue, rest all are working just fine. We are in PKI infra, we installed the agent with exit code 0 (CCMSETUP.log). Reviewed the location services and identified no issues, same with clientidmanager and ccmnotificationagent reports BGB client agent is disabled, not sure if this the issue.
We see policy update is getting updated, find the attached screenshot

Thanks for posting in Microsoft MECM Q&A forum.
Yes, BGB client agent is disabled will cause the issue that client does NOT show as ONLINE.
SCCM client communicates to its MP every 15 minutes to confirm it’s still online. In simple words, when your client is NOT showing as ONLINE in SCCM console then, we may have a problem with the fast notification communication channel. BGB refers to the fast notification communication channel component. There are three components in SCCM CB fast channel notification:
1.Notification manager will be located along with site servers (Primary/Secondary)
2.Notification server will be located along with Management Point (MP) and in secondary sites.
3.Notification Agent is fast channel notification component at SCCM client end.So, please enable the CCM Notification Agent on the problematic SCCM client. If we can't enable CCM Notification Agent, please try to repair or reinstall the SCCM client agent.
For more information about client notification, please refer to:

Overview of Client Online Status in SCCM ConsoleThanks for your time.
Best regards,
Simon
