This functionality makes remote troubleshooting, remote work, and enterprise IT management significantly more efficient.

Why Remote Desktop Access Is Essential for Modern IT Operations

Remote desktop technology isn’t just a convenience—it’s a necessity. As companies move toward distributed teams, cloud adoption, and device-agnostic workflows, remote access supports:

Critical business use cases:

Remote IT support for employees
Access to internal systems securely
Server maintenance without physical presence
Virtualized work environments
Rapid response during technical incidents
Support for multi-location operations

Without secure remote desktop capabilities, organizations face inefficiencies, delays, and increased operational risk.

Key Methods for Remote Desktop Access

There are several ways to remote desktop to another computer, each offering different levels of security, ease of use, and administrative control.

Using Windows Remote Desktop Protocol (RDP)

RDP is the most common and built-in method used across Windows devices.

Benefits:

Installed by default on Windows
Supports encrypted connections
Offers remote control over the entire desktop
Integrates with Active Directory

However, RDP must be configured carefully due to its common exploitation by cybercriminals.

Using Third-Party Remote Access Tools

Many organizations rely on alternative tools for additional features or easier setup.

Popular remote access tools include:

AnyDesk
TeamViewer
Chrome Remote Desktop
Splashtop
VNC platforms

These are helpful when cross-platform access or cloud-based connectivity is needed.

Using VPNs for Secure Remote Connection

A VPN allows secure access to internal networks, providing an additional layer of protection before connecting via RDP.

Benefits of VPN-based remote access:

Strong encryption
Restricted access to internal resources
Reduced exposure to open internet threats
Better compliance posture

VPN + RDP is one of the safest combinations for enterprise use.

Cloud-Based Remote Work Platforms

Solutions like Microsoft Azure Virtual Desktop or Windows 365 Cloud PC provide remote access via cloud-hosted environments.

Advantages include:

Simplified management
High security
Scalable virtual desktops
Centralized software control

These platforms are ideal for large enterprises or high-security environments.

Preparing a Computer for Remote Desktop Access

Before you can remote desktop to another computer, several steps must be taken to ensure it is accessible, secure, and properly configured.

Enabling Remote Desktop on Windows

You must enable remote access settings on the target machine.

Steps typically include:

Opening System Settings
Allowing Remote Desktop connections
Enabling Network Level Authentication
Adding permitted users

This ensures only authorized individuals can connect.

Setting Up Firewall Permissions

Windows Firewall must be configured to allow RDP traffic.

This includes:

Allowing inbound RDP connections
Limiting access to approved IP addresses
Setting port forwarding rules for external connections

Firewall configurations are essential for security.

Configuring Router Port Forwarding (For Home or Small Office Networks)

If connecting from outside a private network, RDP ports may need to be forwarded.

Key considerations:

Forwarding port 3389
Mapping external ports to internal devices
Avoiding unnecessary exposure to the internet

Port forwarding should always be paired with VPN access where possible.

Using Strong Authentication and Secure Passwords

RDP is frequently attacked through brute-force methods, so authentication must be strong.

Best practices include:

Using long, complex passwords
Enabling Multi-Factor Authentication (MFA)
Avoiding shared accounts
Disabling unused local accounts

Stronger authentication dramatically reduces risk.

IP Restrictions and Network Layer Controls

Restricting remote desktop access to specific IP addresses prevents unauthorized attempts.

Ways to restrict access:

Firewall allow-lists
VPN-only access
Network segmentation
Zero Trust access controls

IP filtering is one of the most effective security measures for remote access.

Using Remote Desktop to Access Another Computer

Once the configuration is complete, you can connect from another device.

Typical steps include:

Opening the Remote Desktop Connection app
Entering the target computer’s IP address
Providing credentials
Accepting the security prompt
Controlling the remote machine

Organizations may automate or streamline these processes using device management tools.

Security Risks Associated With Remote Desktop Access

While remote desktop technology is powerful, it must be handled carefully to prevent security vulnerabilities.

Common risks:

Brute-force login attempts
Exposed RDP ports
Outdated authentication
Unpatched systems
Weak or reused passwords
Stolen credentials
Man-in-the-middle attacks

Cybercriminals frequently target RDP because it gives direct access to systems.

Best Practices for Securing Remote Desktop Access

To protect devices and networks, IT teams must implement multiple layers of defense.

Require Multi-Factor Authentication

MFA stops attackers even if passwords are compromised.

Restrict Access Using VPNs

VPNs limit exposure and ensure only trusted users can attempt remote access.

Use Network Level Authentication (NLA)

NLA prevents full RDP sessions until the remote user is authenticated.

Change the Default RDP Port

Although not a primary security measure, changing the port reduces automated scanning.

Apply Regular Updates and Patches

Updates protect against:

RDP vulnerabilities
Privilege escalation exploits
Zero-day attacks

Patch management is non-negotiable.

Disable Remote Access When Not Needed

Attack surfaces should remain as small as possible.

Limit Administrative Privileges

Admin abuse is one of the leading causes of major breaches.
