Thin is In - more

The key choice in both menus is the "Settings" dialog (Figures 6 and 7) because settings is the one place in the thin client user interface where you can see what is going on with your DSD-150 installation. The other choices in both menus take you to the DSD-150's menus (discussed below) or to the thin client popup windows (also discussed below).

There are two critically important buttons on the Settings dialog: "Re-authenticate" and "Service Log". "Re-authenticate" establishes a connection between the client PC and the DSD-150 on your LAN. You need to re-authenticate a client after you power cycle the DSD-150 or if you've unplugged your PC or if you've changed the settings in the DSD-150 menus.

On XP I repeatedly ran into trouble that I eventually traced back to my computer not being able to authenticate to the DSD-150. Without the service log, you have no visible indicator of problems like authentication being the source of an Internet outage.

But after the thin client installed on my Windows XP computer, I was not able to get out to the Internet. Instead, the DSD-150 again showed me Figure 2 and prompted me to download the thin client. I tried again and rebooted. I opened a web browser and was redirected to Figure 2 again. I was able to log in to the DSD-150's administrative web server (see Figure 8) as well as go to D-Link's website and look around the tech support web pages. But, I could not see anything else on the Internet.

The "Chat Live" icon in the lower right-hand corner of Figure 8 seemed to promise that help was at hand, but when I tried it, I got stuck in a loop because my PC needed to authenticate before being able to download the chat client. Fortunately, I was able to phone D-Link support, who quickly traced the problem to XP's software firewall. Once I disabled it, clicked "Reauthenticate" and waited for the thin client to download and do its thing, I was finally granted web access. Life is good!

In summary, the thin client software for the DSD-150 is big, silent, unseen, and hard to diagnose. Your computer will be slower while the DSD-150 back end is pushing software to your client. But, once your client has ingested its software, things return to normal.
