This includes managing critical domain systems such as Active Directory (AD), Certificate Authority (CA), and Windows Server Update Services (WSUS).

The current environment involves hundreds of nodes, including Windows Server instances and Virtual Desktop Infrastructure (VDI) for specific systems, running primarily in an on-premises virtual environment.
