This allows Windows to manage the volume directly. However, in real-world scenarios with Synology NAS and SATA disks, the results can be disappointing.

Maintaining a clean DNS in a non-persistent VDI environment (like VMware Horizon) can be challenging. When VMs are frequently destroyed and recreated, “ghost” records and permission conflicts often lead to connectivity issues. Here is how we restructured our infrastructure to ensure a stable and self-cleaning DNS. 1.
