Technical Details

what runs on :2179

This service carries Microsoft Remote Desktop Protocol traffic for virtual machines over TCP and, where supported, UDP on port 2179. RDP negotiates security and capabilities before establishing framed display, input, device, and virtual-channel streams; modern deployments normally use TLS and Network Level Authentication through CredSSP. Port 3389 is the usual endpoint for ordinary Windows host or guest RDP, while 2179 identifies the Hyper-V virtual-machine RDP service.

security overview

This is a remote-access endpoint and should be restricted to trusted management networks, not exposed directly to the internet. A reachable service can be targeted for password spraying and RDP implementation vulnerabilities, and successful authentication may provide interactive access to a virtual machine or management workflow. Use strong authentication, current Windows patches, firewall allowlists, and monitoring for connection attempts.

service: Microsoft Hyper-V VM RDP
transport: TCPUDP
encryption: tls / encrypted
assignment: iana registered
risk: 7/10risk
category: Remote Access Virtualization
usage: Port 2179 is the Microsoft endpoint for RDP access to virtual machines, particularly Hyper-V VMConnect and enhanced-session connections. Engineers typically encounter it on a Hyper-V host rather than on the guest OS; conventional desktop RDP commonly uses port 3389. IANA lists Brian Henry as the registrant.
