Hi, @Vid3al
Thank you for posting in Microsoft Q&A forum.
- The certificate on the Distribution Point that has the PXE feature active should be automatically renewed. However, if it does not renew automatically, you can renew it manually.
- To manually renew the certificate, you can update the date or time in the "Communication" tab from the "Properties" of the distribution point.
- After renewing the certificate, you should monitor the Distmgr.log and Smsdpprov.log files to understand if the renewal was successful. We can also check the new certificate in SCCM console like below:
- With the expired certificate, it's normal that software distribution in the software center continue to work.
