HTML-XXXX-XXXX Licenses being issued in RD Licensing Manager

358 Views
Last Modified: 2018-03-28
We are a Citrix shop with XenApp 6.5. I only have 200 devices, but over 325 licenses are being consumed. Most by licenses named HTML-XXXX-XXXX, where the X's are random numbers. What are these and how do I eleminate them? I've been revoking licenses daily but I need to solve the root cause here.

I've started purchasing per-user licenses as I will be gradually switching to user from device, but those aren't being issued either, likely because I'm in per-device mode. What is the best way to eliminate these HTML-XXXX-XXXX licenses and transition to the per-user mode?

It is a known issue.

You Create a Citrix Provisioned machine where all the machines are booted from a pre-defined image and all the changes are lost after reboot. So every time the machine connects it gets a new ClientHWID and this is lost on the next boot. The next time the machine connects to the RDS Host, it gets a new Client HWID and hence a new RDS license is issued. Citrix XenDesktop provisioned machine with different hardware ID which can cause the license server to recognize it as different device and issue duplicate licenses?

YOU are correct. There is no fix unless you change the licensing to  per-user mode.

Resolution It is recommended to use Per-User RDS licensing in these scenarios, because the licenses are reverted when the user logs off, hence the number of licenses will not be affected.

I would think these are probably Receiver for Web license checkouts.  And as Jackie pointed out, you should definitely change them to per-user licenses if you are going to use Receiver for Web..

Well, I understand that I can change to a per-user mode. But, I only have 5 user licenses, the remaining 325 are device licenses. So, would I be in violation of licensing, and will it cut me off?

Two, while that is a workaround, how in the world can I fix the root cause? There's no way I can have that many HTML5 clients out there, nor do we use custom images.

Remember.. every browser session is a separate license launch when in per-device mode.  How many actual users do you have?  that will obviously drive if you can/should switch to per-user.  If you have too many, then you absolutely should disable Receiver for Web, that should eliminate those licenses from being issued.  

but, ideally you'll be able to switch to per-user, and that problem should go away.  As long as you have the right number of user licenses, then I'm sure MS would be ok with it.. but you can check with your licensing specialist to be 100% sure.

So, if I keep killing these HTML licenses, it really won't affect anything, or prevent users from logging in. I just need to increase my user licenses and switch to per-user mode, correct?

Does switching modes require downtime? Anyone done this before personally?

There is no downtime for switching modes... once they are logged in, the license checks are complete.  It would only affect someone logging in at that exact moment.  Killing the licenses should be just fine from a technical perspective.
