In this blog entry, I shared various perspective about how wonderful NComputing is. Here is a problem, though, and a solution one Texas technology coordinator shared:

Xtendas freezing and sluggish with some web-based apps? It could be your browser. nComputing tech support suggested that IE doesn’t like running several instances of itself, and may be causing the freezing with web apps and our Xtendas. At their suggestion, we downloaded sandboxie and pushed the application out to all of our Xtenda base machines. It seems to have alleviated the freezing when web apps are accessed on the extended desktop. We just pushed it out this week, but already we are seeing a difference. I am hopeful this did the trick.

In a nutshell, with sandboxie installed, programs run in an isolated environment and minimizes issues. REad more about it on the website. Its a free download.

Here’s an explanation:

Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer.

• Secure Web Browsing: Running your Web browser under the protection of Sandboxie means that all malicious software downloaded by the browser is trapped in the sandbox and can be discarded trivially.

• Enhanced Privacy: Browsing history, cookies, and cached temporary files collected while Web browsing stay in the sandbox and don’t leak into Windows.

• Secure E-mail: Viruses and other malicious software that might be hiding in your email can’t break out of the sandbox and can’t infect your real system.

• Windows Stays Lean: Prevent wear-and-tear in Windows by installing software into an isolated sandbox.

Interesting…in the meantime, here’s an email from NComputing’s own John C. Rippen, a Sales Support Engineer on the subject. The email appears in its entirety:

Hello Miguel,
I’m part of NComputing’s technical support organization, and I saw that you’d posted something here (http://www.mguhlin.org/2009/02/ncomputing-trouble-shooting.html) regarding the use of Sandboxie when using NComputing.

No big issue, but it is a slight concern to me that the individuals you spoke with seem to have misinterpreted the original issue. I’d like to clarify (and respectfully ask for you to update this on your blog) that Internet Explorer has no inherent need to be sandboxed; in that specific case, it was that a specific Java script that was running inside of the website was not “multi-user friendly” and so the specific javascript had to be sandboxed, and it just so happened that the most expedient way of sandboxing the javascript was just to run the whole browser in a sandbox.

So, this was more of a corner-case than anything else. Internet Explorer 6 and higher is fully capable of running in a multi-user situation in almost every other respect; Microsoft’s own Terminal Services depends on IE being as multi-user friendly as possible. Like I said, it’s no big issue, I’m just trying to make sure that information about our technology is as technically accurate as possible.

Have a good day J
