Hi Dom,
Thank you for posting in Microsoft Q&A forum.
It seems that remnants of this decommissioned server's configuration still exist in your SCCM environment. Is this decommissioned server a MP? Please try the following:
1,Check your Active Directory and ensure that all Active Directory records and objects related to the decommissioned server are removed. This includes computer objects, DNS records, and any SCCM-specific attributes associated with the server.
2,Open the SCCM console and navigate to "Administration" > "Site Configuration" > "Servers and Site System Roles." Make sure that the decommissioned server is not listed there. If it is, remove it.
3,Restart the "SMS_EXECUTIVE" service on the SCCM site server. This might help refresh the SCCM component's configuration and potentially resolve issues related to the decommissioned server.
Thanks for your time. Have a nice day!
Best regards,
Simon
