What is Remote Access Connection Manager?

The Remote Access Connection Manager (RASMan) is a core Windows service that enables your system to establish and manage remote network connections—especially VPNs and dial-up networking. While it runs quietly in the background, it plays a critical role in allowing secure connections from your computer to a corporate network or remote device.

Without RASMan running in the background, features like remote access, VPN clients, or even some remote desktop apps might stop working correctly.

What does Remote Access Connection Manager do?

RASMan plays a behind-the-scenes but essential role in remote connectivity. Its core responsibilities include:

  • Manages VPN and dial-up connections: RASMan initiates, maintains, and terminates VPN or dial-up sessions—essential for remote teams and secure access to corporate networks.
  • Handles user authentication: It ensures that only authorized users can access your system remotely by verifying credentials.
  • Facilitates communication with remote resources: Acts as a bridge between local systems and remote networks, allowing seamless data exchange and session control.
  • Supports dependent services and remote access tools: Tools like Remote Desktop and VPNs rely on RASMan, making it essential for any remote desktop manager used in enterprise IT.
  • Integrates with RRAS (Routing and Remote Access Service): Enables advanced features like network routing, NAT, and VPN management in enterprise setups.
  • Works with Remote Access Auto Connection Manager: Automatically connects to preferred networks when users access remote resources, saving time by avoiding manual setup.

In short, it is the link between your local system and remote networks, especially in Windows environments.

Difference between RASMan (Remote Access Connection Manager) and RDCMan (Remote Desktop Connection Manager)

While their names sound similar, RASMan and RDCMan serve entirely different purposes:

  • RASMan is a Windows service responsible for managing remote connections, especially VPNs and dial-up. It works in the background to support network-level connections.
  • RDCMan, on the other hand, is a Microsoft utility used to organize and manage multiple remote desktop sessions. It’s a tool that IT professionals use for convenient access to various remote machines from a single interface.

Why is RASMan important for remote work?

Without RASMan, many remote work essentials break down—it’s key to secure, stable remote PC access. For example:

  • VPN clients won’t establish secure tunnels
  • Remote desktop software may fail to connect
  • System admins cannot manage remote servers or endpoints
  • Network diagnostics via remote sessions become unreliable

If you're using a remote desktop solution, RASMan ensures that background networking services are functioning properly to ensure smooth, uninterrupted access. It’s also a key enabler for remote desktop sharing, where users collaborate or provide support by viewing and controlling desktops remotely.

How do I enable Remote Access Connection Manager?

If your VPN or remote desktop isn’t working properly, first check if the RASMan service is enabled. Here’s how to do it:

  • Press Win + R, type services.msc, and hit Enter
  • Scroll down and find Remote Access Connection Manager
  • Right-click and select Properties
  • Set the Startup type to Automatic
  • Click Start if the service isn’t already running
  • Hit Apply and OK

Now try reconnecting using your remote desktop or VPN software—it should work fine if RASMan is running.

Troubleshooting: RASMan service isn't running on my computer

Seeing errors like “RASMan isn’t running” or “Connection failed because the Remote Access Connection Manager is not running”? Here’s how to fix it:

  • Start RASMan Manually

    • Open the Services window (services.msc)
    • Find Remote Access Connection Manager
    • Right-click → Start, or check that the Startup Type is set to Automatic

  • Enable Dependent Services

    Ensure the following services are running:

    • Remote Access Auto Connection Manager
    • Remote Procedure Call (RPC)
    • Secure Socket Tunneling Protocol (SSTP)
    • Telephony

  • Check for Windows Updates

    Go to Settings > Update & Security and install the latest updates. These can fix bugs affecting background services.

  • Run System File Checker

    Use Command Prompt (Admin) and enter:

    sfc /scannow

    This scans and repairs corrupted files that may block RASMan.

  • Reset Network Settings

    Open Command Prompt as Admin and run:

    netsh winsock reset

    Once you've restarted your PC, test your remote desktop connection again to ensure the issue has been resolved.

    Bonus Tip: If RASMan Still Won’t Start

    • Run the Network Troubleshooter under Network & Internet settings
    • Scan for malware, which may disable critical services
    • Create a new Windows user profile if the current one has permission conflicts.
