Fix Server 2016 Drive/RDP

I recently added a new physical drive to our Windows Server 2016 machine and, right after the change, two critical problems showed up: Remote Desktop refuses to connect (no specific error, it just never reaches the log-in screen) and the new drive is not visible anywhere in Disk Management or File Explorer. All other settings were left untouched; the only operation was plugging in and initializing that additional disk.

I need a Windows Server specialist who can securely remote in, diagnose what I overlooked, and bring both the RDP service and the missing drive back online. Typical areas to inspect could be disk initialization/partitioning, drive letter assignments, storage pool or RAID configuration, as well as RDP-related firewall rules, NLA settings, and service dependencies—whatever is necessary to restore normal operation.

Deliverables (must-haves)
• Working Remote Desktop connection, tested from an external client.
• Newly added drive fully mounted and accessible in File Explorer.
• Brief summary of the root cause and the exact steps you took so I can document them for future reference.

You’ll be given temporary administrator credentials for direct access. Once the job is confirmed fixed, I’ll close the session and revoke access. If you have questions before starting, just let me know.
