Microsoft Windows Server Remote Access Technologies

Description

Remote access to server Desktops is important for both administrative usages and end-user support purposes. From an administrative standpoint, Remote Desktop can be used to access servers, manage their desktops, and run installed applications across the network. From an end-user standpoint, Remote Desktop Services (RDS) can be deployed so that users can run applications on servers, access personal desktops on servers, or even access entire virtual machines based on Hyper-V.

The protocol used by both Remote Desktop and RDS is the Remote Display Protocol (RDP). When planning for access to remote desktops across the Internet, security is an important consideration. You should use a Virtual Private Network (VPN) connection, such as PPTP, L2TP/IPSec, or SSTP to secure the link. Alternatively, you can use RD Gateway to access RDS servers, which will utilize HTTPS to encrypt data communications. An enhancement to the RDP protocol with the release of version 6.0 was application virtualization. This version of the protocol allows applications to run on the server but appear to run on the local desktop to the accessing user.




EXERCISES

  • Enable Remote Desktop on the server.
  • Connect to the server using the Remote Desktop Connection client in Windows 7.
  • Create a Remote Assistance request.

Answers for Exercises

  • Use the instructions provided in the “Remote Desktop versus Remote Desktop Services” section in this chapter to enable Remote Desktop. While you’re in the interface, click the Select Users button to see how you can add users other than the Administrators group for access via Remote Desktop.
  • Use the instructions in the “Desktop in the Remote Desktop versus Remote Desktop Services” section in this chapter to create the connection. While the connection is being created, be sure to click the Options down-arrow and browse through the tabs to see the available options.
  • Use the instructions in the “Understanding Remote Access Solutions” section in this chapter to create the Remote Assistance request and save it as a file. You can perform this action on a Windows Vista or Windows 7 machine as well.




REVIEW QUESTIONS

  • 1. Which VPN protocol is supported by the most Windows systems, but provides less security?
    • A. PPTP
    • B. SSTP
    • C. L2TP/IPSec
    • D. RDP
  • 2. True or false: By default Remote Assistance is enabled on Windows Server 2008 and Windows Server 2008 R2.
  • 3. What VPN protocol uses SSL?
    • A. PPTP
    • B. SSTP
    • C. L2TP/IPSec
    • D. RDP
  • 4. What protocol is used for communications with the RD Session Host server from the Remote Desktop Connection client?
  • 5. What dialog box is used to enable Remote Desktop on Windows Server 2008?
    • A. Computer Properties
    • B. Server Properties
    • C. System Properties
    • D. Remote PropertiesDP
  • 6. Define Remote Desktop Services.
  • 7. Define encryption.
  • 8. Which one of the following RDS role services allows users to run applications within a web browser?
    • A. RD Virtualization Host
    • B. RD Session Host
    • C. RD Licensing
    • D. RD Web Access

    • A. RD Gateway
    • B. RD Session Host
    • C. RD Licensing
    • D. RD Web Access
  • 10. True or false: Without IPSec, L2TP is a tunnel-only protocol.

Answers for Review Questions

  • 1. A PPTP has been supported in Windows since the 1990s, but it is the least secure of the supported protocols.
  • 2. False Remote Assistance is a feature that must be added to the server. Remote Assistance is installed by default for the clients, but not for the servers.
  • 3. B The Secure Sockets Tunneling Protocol (SSTP) uses SSL and, therefore, port 443 by default.
  • 4. Remote Desktop Protocol. RDP has been used since Windows NT 4.0 Terminal Server Edition, and it is on version 6.1 in Windows 7 and Windows Server 2008 R2.
  • 5. C The System Properties dialog box is used. The Remote tab allows for the configuration of Remote Assistance and Remote Desktop.
  • 6. The server role in Windows Server 2008 and R2 that allows for remote Desktop control using the Remote Desktop Client software.
  • 7. The process used to convert plaintext or readable text into ciphertext. Encryption can be used on any data because all data is represented by binary numbers within computer systems. The input to the encryption algorithm is one set of binary numbers and the output is another. The algorithm can both scramble and descramble the data.
  • 8. D RD Web Access allows users to run applications or entire Desktops in a web browser using an ActiveX control.
  • 9. B The RD Session Host is the component that actually allows servers to host applications or entire Desktops for remote control and access.
  • 10. True IPSec provides the encryption and authentication for L2TP. L2TP is simply responsible for establishing the tunnel.
