Access Denied - You don't have permission to access ...

We've noticed a number of you who are encountering an error when attempting to access the VMware Knowledgebase, whether it be the main landing page, or a specific article in the KB. You see something like:

Access Denied - You don't have permission to access "http://kb.vmware.com/" on this server.

We are aware of the problem and are investigating the issue on our servers, but in the meantime we want everyone to know the work-around. Go into the menu of the browser you are using and clear both the cookies and the cache.  Then reload the KB URL - it should then work.

We apologize for this inconvenience.

VMware Thinclient FAQ

VMware ThinclientWhat are zero clients and thin clients you ask? No, they’re not skinny customers, they are hardware devices which rely on the server to do most of the work while they serve merely to deliver input and output back and forth for the user.

Our research tells us many of you are wondering about zero clients and thin clients; their differences and function. Read on as we explain your client options for VMware Horizon View.

What’s the difference between a thin client, thick client, and a zero client?

Zero clients have no local storage, operating system or CPU, just a chip that decodes PCoIP at the hardware level and renders the pixels onto the user’s display. Benefits of a zero client include highly efficient energy use, and next to no device management – just configure and deploy.

Thin clients are similar to zero clients on the outside, but contain a CPU, memory, storage and an operating system to make them run.

A thick client would be a regular laptop or desktop, running a standard OS and the software client. These clients of course are the most expensive to run and maintain.

Why would I want a thin or zero client?

  • Extremely efficient energy use.
  • Huge cost savings vs purchasing thick clients.
  • Ease of deployment and management.
  • No data is stored on device so perfect for secure environments.

What are the advantages and disadvantages of these types of clients?

Zero Client

+ Less overhead and maintenance.
- Can be protocol specific, so if you change infrastructures you may need new devices.
- USB devices may become more complicated to use.

Thin Client

+ VPN connectivity options.
+ More supportability for USB devices.
- More software updates than a zero client, but less than a thick client.

What other connection options are out there?

Windows software client

VMware Horizon Client for Windows makes it easy to access your Windows virtual desktop with the best possible user experience on the Local Area Network (LAN) or across a Wide Area Network (WAN).

  • Support for Windows 8 and 8.1 (with Updates) and Windows 7 systems - With Horizon Client 3.3, support for Windows XP and Windows Vista has been discontinued. See What's New.
  • Unmatched performance - The adaptive capabilities of the PCoIP display protocol are optimized to deliver the best user experience, even over low-bandwidth and high-latency connections. Your desktop is fast and responsive regardless of where you are.
  • Simple connectivity - Horizon Client for Windows is tightly integrated with VMware Horizon 6 for simple setup and connectivity.
  • Secure from any location - At your desk or away from the office, your data is delivered securely to you wherever you are. SSL/TLS encryption is always used to protect user credentials, and enhanced certificate checking is performed on the client. Horizon Client for Windows also supports optional RADIUS and RSA SecurID authentication.

Mac software client

Horizon Client for Mac OS X makes it easy to access your Windows-based remote desktop or application from your Mac with the best possible user experience on the Local Area Network (LAN) or across a Wide Area Network (WAN).

  • Support for Mac OS X Snow Leopard (10.6.8), Mac OS X Lion (10.7), Mac OS X Mountain Lion (10.8), Mac OS X Mavericks (10.9), and Mac OS X Yosemite (10.10) - Use a 64-bit Intel-based Mac to work on your Windows-based remote desktop or application.
  • Unmatched performance - The adaptive capabilities of the PCoIP display protocol are optimized to deliver the best user experience, even over low-bandwidth and high-latency connections. Your remote desktop or application is fast and responsive regardless of where you are.
  • Simple connectivity - Horizon Client for Mac OS X is tightly integrated with View for simple setup and connectivity. Quickly reconnect to your remote desktop or application by selecting from up to eight View server shortcuts in Horizon Client.
  • Secure from any location - At your desk or away from the office, your data is delivered securely to you wherever you are. Enhanced certificate checking is performed on the client. Horizon Client for Mac OS X also supports optional RADIUS and RSA SecurID authentication. (RADIUS support was added with VMware View 5.1 and Horizon Client for Mac OS X 1.5 or later.)

Linux software client

VMware Horizon Client for Linux makes it easy to access your Windows virtual desktop from a supported Linux system with the best possible user experience on the Local Area Network (LAN) or across a Wide Area Network (WAN).

  • Support for Ubuntu 12.04 or 14.04, Red Hat Enterprise Linux (RHEL) 6.5, SUSE Linux Enterprise Desktop (SLED) 11 SP3, and CentOS 6.5 - The Horizon Client 3.2 installer provides support for these operating systems.
  • Unmatched performance - The adaptive capabilities of the PCoIP display protocol are optimized to deliver the best user experience, even over low-bandwidth and high-latency connections. Your desktop is fast and responsive regardless of where you are.
  • Simple connectivity - Horizon Client for Linux is tightly integrated with VMware Horizon for simple setup and connectivity.
  • Secure from any location - At your desk or away from the office, your data is delivered securely to you wherever you are. Enhanced certificate checking is performed on the client. Horizon Client for Linux also supports optional RADIUS and RSA SecurID authentication.

HTML Access

HTML Access makes it easy to access your Windows virtual desktop from an HTML 5-based browser; no need to install any software.

  • Access View desktops from device platforms where no native client is available, or from any computer on which you do not want to install software. You can also select HTML Access from a VMware Workspace Catalog.
  • HTML Access is tightly integrated with VMware Horizon 6 for simple setup and connectivity. Open a browser, enter a server URL, and log in to see a list of available View desktops.
  • At your desk or away from the office, your data is always secure. Enhanced certificate checking is performed on the client. HTML Access also supports optional RADIUS and RSA SecurID authentication.
