Windows 8.1 and Netscaler Gateway Plugin

Yeah, Windows 8.1 is here!

Update #3, June 26th 2014: Netscaler 10.1 build 123.x has full support for Windows 8.1. Upgrade to the latest build to benefit from the latest features in Netscaler and Netscaler Gateway.

Update #2, Oct 25th: An updated Gateway plugin will be available in about a week from today. See comments on this post: http://blogs.citrix.com/2013/10/24/receiver-for-windows-4-1-update-adds-support-for-windows-8-1/, And by the way, Receiver 4.1 with Windows 8.1 support is out.. 🙂

Update Oct 25th: A reader suggested a workaround to get around this problem. See the comments for more information.
A new release of Netscaler Gateway and the plugin has just been made available by Citrix. If I get around to test this soon, I will update this post with more information.

Update Oct 21st: Citrix are releasing updated versions of some of their products on October 23rd that adds support for Windows 8.1 and Windows Server 2012 R2. One of those products is XenDesktop 7.1. I do not know if this includes an updated version of Netscaler Gateway or NG Plugin.

And now, back to REAL life. For those of you out there that uses the Netscaler Gateway Plugin (NGP) in your deployments (not to be confused with EPA plugin), take a step back. At least from upgrading to Windows 8.1

NGP does not support Win 8.1 as of the time of writing (version 10.1-120.13). Period. What happens is that the plugin seems install just fine, but it is never activated. When the user then logs in on the Netscaler, the Java version of NGP will be used.

The drawback here, is that when the login is successfull, the user is prompted to change is browser proxy configuration to point to 127.0.0.1:3125, which is the Java NGP. This effectivily leads all web browser trafikk towards the Netscaler, also traffic destined to ordinary internet sites. That is not always something you want, or at least need.

To top of this, when the user logs off, he/she is prompted to reset the proxy configuration in the browser. This behaviour is not exactly user friendly, and an annoyance at best. At worst, the user might not be able to change this configuration to start with, and might not know how to do it at all.

So, what to do? Well, in short…advice your users NOT to upgrade to Win8.1 yet, if access through the Netscaler is important to them. This is bad, since Windows 8.1 is pretty good. 😛

    This will fix your problem for now:

    reg add “HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent” /v Platform /t REG_SZ /d “Windows NT 6.2”

      Thank you Anton! I just tested this on one computer with Windows 8.1, and it does indeed seem to work. I’ll be forwarding this to a collegue who will be testing this as well.

        What Windows 8 version/variant are you using, and what browser?
        About the gateway plugin, you have to use the version that the Netscaler gateway in question comes with, you can’t use a newer or older version.

        You may also try to uninstall Netscaler Gateway Plugin, and reboot the computer. Then try to login on the site again, and install the plugin when prompted. NB: You will have to use Internet Explorer to make it work. Unless you are using a Mac, of course. 🙂

        This might require that you have admin rights. Start command prompt, and run the command as you see it here, starting with “reg add….”

        Good! 🙂 It’s probably the quotes causing problems, there are different characters being used on, ” and ‘

      Using Win 8.1.
      I am now using the one that is given by the site on a Win 7 machine. This is because I never get prompted to download anything when I login (even though I have no gateway plugin installed)… Tried in internet explorer (v11) but still it’s not helping:(

        Ok. Please check in Program and features in Control Panel, and find Citrix Access Gateway plugin there. Check the version i the right-most column. If here version is lower then 10.1.120, you might av an issue. The version was not compatible with Windows 8.

        Version 9.1 is quite old, and will need an upgrade to work with Windows 8. That version doesn’t even support Internet Explorer 10 or later, unless you use compatibility mode. Unfortunately, it’s not enough to upgrade the plugin, the Netscaler it self needs to be upgraded or replaced.

        The procedure is described further up, see the comment from “Anton”. It will probably work best if you type it in manually starting with “reg add….”, rather then copy – paste.

      Yes, it does look very promising. I’m still waiting for confirmation from a customer, but I’ve successfully testet this myself on two separate computers. Seems like the Plugin needs a reset after the change (ie. reload nsload.exe), but after that it’s no problem.
      EDIT: I had some problems running the command, and ended up creating the registry key manually. That fixed it.
