Issue with Temporary Profile on Windows Server 2025 after renaming built-in Administrator account

Hi everyone, I am facing an issue with a temporary profile on Windows Server. Environment details: ・OS: Windows Server 2025 Datacenter ・Setup: On-premises environment with 2 servers (AD DS Domain Controller and Web Server) ・Affected Server: Web Server (Domain joined) Recently, I renamed the built-in Administrator account on the Web Server. After that, the system became completely unresponsive, so I had to force a power off.
