Introduction

RDP (Remote Desktop Protocol) is a protocol developed by Microsoft that allows you to remotely access and manage Windows Server operating systems with a graphical interface. With your REXE Technology VDS server, you can connect via RDP to manage your Windows Server as if you were sitting in front of it.

Prerequisites

InformationDescription
Server IP AddressViewable from the REXE panel
UsernameUsually Administrator
PasswordSent via email after setup
PortDefault: 3389

Your server credentials are automatically sent to your email address after ordering.

Connecting from Windows

Using Remote Desktop Connection

  1. Press Windows + R to open the Run dialog
  2. Type mstsc and press Enter
  3. Enter your server IP address in the Computer field
  4. Click Connect
  5. Enter your username and password
  6. Accept the certificate warning and click Yes
mstsc /v:SERVER_IP_ADDRESS

Custom Port Connection

If you've changed the default RDP port:

mstsc /v:SERVER_IP_ADDRESS:PORT_NUMBER

Connecting from macOS

  1. Download Microsoft Remote Desktop from the App Store
  2. Click Add PC
  3. Enter your server IP address
  4. Add your credentials (username and password)
  5. Click Connect

Connecting from Linux

Use Remmina or xfreerdp:

hljs bash
# Using xfreerdp
xfreerdp /v:SERVER_IP_ADDRESS /u:Administrator /p:PASSWORD

# Using Remmina
# Open Remmina → New Connection → RDP → Enter server details

Path Panel Firewall Settings

On REXE servers, when an IP has no rules at all, all ports are open. However, the moment you create your first filter rule, the system automatically adds Default Block and only the ports you allow stay open. To secure your RDP access (and to maintain access if your IP already has other rules), create a filter rule for the RDP port (3389) via Path Panel or the Rule Management product in your customer panel:

  1. Log in to Path Panel or the Rule Management product in your customer panel
  2. Click on the relevant IP address
  3. Create a new filter rule:
    • Protocol: TCP
    • Destination Port: 3389 (or your new port if changed)
    • Description: RDP access
  4. Wait for the rule to reach propagated status

The rule creation screen has two modes: standard filter (protocol + port only) and hard filter (you pick one of the game or application filters). For RDP the standard mode is enough; both modes operate at Layer7 and track connection state, the only difference with a hard filter being application-specific packet inspection, and TCP Symmetric is just one of those hard options.

Security Recommendations

  • Use strong passwords: RDP brute-force attacks are common
  • Enable NLA: Network Level Authentication adds an extra security layer
  • Consider changing the RDP port: Using a non-standard port reduces automated attacks
  • Keep Windows updated: Regular security updates are essential

For maximum security, combine NLA with strong passwords. The standard filter (protocol + port) is enough for RDP.

Performance Optimization

Connection Quality Settings

To improve performance on slow connections:

  1. Click Show Options in the RDP connection window
  2. Go to the Experience tab
  3. Select the profile matching your connection speed
  4. Disable unnecessary visual effects (wallpaper, font smoothing, etc.)

Screen Resolution

Connect with a custom resolution from the command line:

hljs bash
mstsc /v:SERVER_IP /w:1920 /h:1080

Common Issues

IssueSolution
Connection timed outCheck the Path panel firewall rule
Credentials don't workVerify username (Administrator) and password
CredSSP errorUpdate your local Windows or adjust NLA settings
Black screen after connectingWait a moment, or restart the server from the panel
Slow connectionDisable visual effects in the Experience settings

Conclusion

RDP is the easiest way to manage your Windows Server VDS with a graphical interface. You can protect your server with security measures like enabling NLA, changing the port, and account lockout policies. If you experience connection issues, first check the Path panel firewall settings.

Frequently Asked Questions

Why is my RDP connection timing out?

If your IP has rules, Default Block is automatically active and disallowed ports are closed. You need to create a filter rule for the RDP port (3389) via Path Panel (x.rexe.tr) or the Rule Management product in your customer panel. If your IP has no rules at all, all ports are open and the problem may be on the server side.

Which filter should I use for RDP?

For RDP the standard filter mode is enough — just enter Protocol TCP and Destination Port 3389. TCP Symmetric is a hard filter (Layer7) and is only needed for highly sensitive applications.

Is RDP connection secure?

RDP uses encrypted connections by default. To further improve security, enable NLA (Network Level Authentication), change the default port 3389, and create a filter rule for the RDP port (3389) in Path Panel. Hard filter (Layer7) options like TCP Symmetric are only needed for highly sensitive applications.
