Asked by selleryp. We have a very simple XenApp setup, where users launch an application from an external URL and this in turn establishes and RDP session onto the server, which is where the applications are installed.
The solution has been up and running for several months now, but on rare occasions we experience a couple of different issues which cause downtime for our client:. Users receive a Protocol Driver Error when trying to launch any of the applications. Failed to run discovery Citrix.
DiscoveryServiceException, Citrix. Users receive a 'Cannot Start App' error when attempting to launch application. Citrix Studio shows the machine as 'Unregistered'. Desktop unavailable com.
When both issues occur a reboot of the server has resolved the problem, but I am understandably concerned why these issues are happening in the first place, as it is causing downtime to our client. Monthly Windows patching is performed out of hours on this server, so it is regularly rebooted as part of this process.
It's very possible that both of these errors are caused by the same problem. The protocol driver error has always been a rather generic error and I've found that it usually means the client isn't able to talk to the citrix server.
I used to see this quite often with linux based thin clients that were not getting IP addresses, but it can be many things. It sounds to me like your VDA is going out to lunch and not coming back! That should help identify the problem.

I have no training in Citrix. My googling tells me that this is an issue on the other side, however, they are insisting it's an issue with our desktops.
This is also kind of long and convoluted, sorry. We have access to another facility's EMR, via Citrix. This arrangement has worked very well for quite a while, although, they haven't let me know about some changes over the years until after they started affecting staff here. We had a complete system down emergency a few weeks ago, due to a transformer outside the clinic exploding. Since that time, we've had a ton of users having issues connecting to the other facility's Citrix farm.
Google tells me that this on the server side. The staff over the servers told me to delete the user's profile from their computer and that should fix it. I can't really delete that without causing a big fuss, though.Compro novillas cebu
On a whim, I noticed that one of the user's had a folder redirection error, they weren't owner of their home folder. Until they logged out and back in. Then the error came back.
12649: Drake Hosted - Citrix Receiver or Workspace FAQs
Deleting the ICAClient folder doesn't seem to help any more. Also, to make things really strange, if people log in via our VDI system, it works fine, most of the time. Good detective work, hopefully that's the culprit. It would be interesting to see whether those systems that do have access can also reach port of one of the XenApp servers.
Hmm as this is happening in the majority of cases, it should be fairly quickly to narrow down what's going on. Are you able to access their citrix from an alternate location e.
It would rule out whether or not the issue is site based or on their side. You should be able to also start to trend whether or not there a commonality by capturing the ICA files as you are attempting to launch applications.
Google should return you results on how to so this. When you open the text file you will be able to see what server it is connecting to. If it's always the same server; then something is awry on their side that needs sorting. I'll see what I can find for that Citrix Receiver utility. My current suspicion is something with our home share.About this release. System requirements and compatibility.
