Hello fellow Citrix engineers, we are facing an issue of high retries on VDAs through PVS provisioning. Found this Citrix Article: https://support.citrix.com/article/CTX222944/troubleshooting-retries-on-provisioned-virtual-machines but after my call with network and storage team, everything looks good. Please note we are rebooting VDAs daily overnight, therefore, we shouldnt receiving retries number such as 800 or some times over 1000. We have 90 VDAs on both sites and we have over 10 affected VDAs daily.
We have rebalance all VDI infra. on hosts and "isolated" PVS servers to mitigate the risk of vDisk streaming on VDAs after the schedule reboot.
As mentioned, talk to the network team, bandwidth looks good and also storage does not have anything "abnormal" behavior.
If retries exceed further on affected VDAs, VDAs are going unresponsive, therefore, we must reboot affected VDA and users must logoff and login to new VDA. This has an impact of losing unsaved work which is not acceptable by any management since user is logging off and not disconnected. Please note, so far, retries does not increasing after they reach to 800-1000 retries number.
Has anyone face similar problem and how do we solve this?

Hello fellow citrix engineers,
Currently, I am working with 2 clusters VDI infrastructures which include 6 DDC (3 on each site) and multiple VDAs. Until now, multiple-session VDAs from both clusters are connecting randomly to DDC on both sites again.
I was curious, if you can somehow manage to connect SITE A VDAs to SITE A DDC and the same for SITE B?

Spectre/Meltdown are enabled by default with Server 2019. Due to our hardware limitations we had to disable the fix via registry. Even with that said, 2019 is slower compared to 2012 R2. Microsoft made a lot of changes around the OS handles things, due to security and our applications run slower on the OS.
Thank you for your reply. I will keep that in mind and try to see how I can optimize this.

Narrow down as to what they mean by slow user sessions.
Are you talking screen redraws? File copies? Mouse movements?
Are the users on-site or remote?
Do they go through a netscaler or VPN?
User are on-prem, although, logon time is slow (we have followed WEM optimization Citrix Article) and compare to Win2012R2 their logon time has increased dramatically.
Additionally, "Interactive Session" time has also been dramatically increased compared to our Win2012R2 image.
Our users they connect to their VDI session via CWA connection.

Have anyone face any similar situation as the screenshot below?
I`ve been facing it randomly the past months but haven't identify why this is happening? Also, after user seems "Failed" in Director, he cant login to his session and we must wait over 30 minutes or the next day until he can successfully login. Please keep in mind that, I cannot see the VDA that he used to be, therefore, i cannot manually "kill" his session.

Hello, does anyone else facing issue with slow user sessions after migrating from windows 2012 R2 to windows server 2019?
After we completed the migration, users started reporting slow user experience but we have checked:
- Local disk free space - Clean
- CPU & Memory - Clean
- Procmon logs - Clean
- Citrix Optimization Tool
Does anyone know face something similar, and if yes, how did you resolve it?

Hello, have anyone else faced video glitching when their users are setting a background image on Teams application? Our problem is, when users just open camera, video is great but when they choose blurry or image background, video start glitching.
CPU and Memory on VDA are balance resourced and Teams optimization documentation from Citrix has been follow accordingly.

Hello fellow Citrix engineers ,
I would like to ask what permissions do I have to change on "Citrix Studio -->Administrators-->Roles" in order, administrators on that role be able to see "Session Details -->Session Control"?

Does anybody knows how Teams folder structure can impact the user behavior?
On our existing image on Windows server 2012 R2, Teams folder is located under:
BUT, with the Windows server 2019 folder redirection, Teams folder is located on one directory further:
My question is, how does this affect user behavior? Will users lose files? Will users require to insert their logon credential?
I`m asking this question because we are in the process to move Win2012R2 users to Win2019 image.
Thanks in advance,
Constantinos

Firstly, WEM is probably doing you a favor by not redirecting that amount of folders - noone should be redirecting things like AppData etc anymore, that's asking for problems. So if we focus on desktop and documents and pretend the rest isn't happening... ?
What path are you using for the redirection, we will need to understand what WEM is being asked to do
Additionally, is anything else in the environment doing folder redirection, or has it done so previously?
What do your shell folder keys show you in the registry as it relates to folder redirection?
Thanks James for your prompt reply. If there is a "Redirection Option" in WEM, it shouldn't make us "a favor" since its given (talking about AppData).
To your though of "what WEM is being asked to do" simple when I open user`s wem.log file, it show an exception with no further detail.
Nothing else does folder redirection since we have already have a Win2012R2 image that works fine for us but since 2012 going EOL we need to upgrade it to 2019.

Hello fellow citrix admins, I have the following issue:
WEM folder redirection does not work on specific folders for Windows Server 2019 image, even though we apply the WEM policies as follows: "Policies and Profiles" --> "Folder Redirection"
*Checked boxes, should redirects folders to the "data folder" of the user. but as per my screenshot above, AppData and Downloads are not redirected correctly BUT "WEM Resultant Actions Viewer" shows it redirects (AppData) & Downloads folder correctly. User if save something in Download folders, it stores in "C:/" which in our case is wrong.
Infrastructure:
- Citrix Components 1912 CU4
- VDA 1912 CU6
- WEM 2305
- PVS 1912 CU4
Troubleshooting done so far:
- Upgrade to the latest WEM version 2305
- Disable AV
- Insert VDA to an OU where no GPOs were applied
- Tried SingleSessionOS and MultiSessionOS
- Tried with different machine catalog
- Tried with new WEM configuration Set

There is no official documentation on it. It is a business decision/user workflow decision.
If you ask microsoft they will say up your cpu and ram and launch it at login.
If you ask Citrix they will say remove it from startup for faster desktop load time.
Thanks you Jeff, smart answer and base on reference here you are kinda corrert Citrix recommend to Disabled but Microsoft recommend to be Enabled.

Thank you Jeff and James for your help, one last question, where do I find best practices for that particular topic "Teams - AutoStart" and I mean from an official documentation. I completely understand that this is a business decision but I need the "evidence" to prove it to our customer.
-
Hello fellow Citrix Engineers,
Where could I find more official documentation about Teams AutoStart best practices for Citrix PVS infrastructures? Asking this because we are observing outrage VDA resources consumption on users` bursting logon time and would like to check if its something that is recommended to customers or not (disable)? And if it`s recommended to be AutoStart=Enable, what are the minimum VMs resources spects to be recommended?
-
So, since this forum haven't really got an official answer from Citrix...I have opened a Case Ticket and revert back with their answer. We have recently upgraded to WEM 2212 but this error did not pop up right away from the upgrade. Something must be triggering this. we use PVS, and it does not happen to all of our VDAs but to the most of them.

Hello all,
It is recently been reported from users that Outlook stays on foreground. We use WS2K12 Multisession but even tho is a known issue for microsoft, couldnt find any relevant articles about Outlook stuck on foreground and VDI. Additionally, I open a case ticket with Citrix and they came up with the great recommendation of testing if this still persists on users that are using CWA through web browser instead from their virtual desktop. Do not know what this has to do with thin client or not but looks like they wanted to avoid it.

Hello guys, first time posting on citrix forum, in my case, we have a customer with over 1200 sessions with Citrix Workspace App. 21.12.0.18 and ICA: 3.3.487d-BOCd-k510-x64-220211. Customer receives around 60 user connection failures which makes the whole situation really frustrated "why user connection failure are not to 0". Additionally, Failure Type: Client Connection Failure and Failure Reason: other which base https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/director/failure_reasons_troubleshooting.html not makes sense, since when users trying to establish a session connection it fails and when they retry, they connect. Therefore no CDF can be gathered on this scenario...
We cannot test https://support.citrix.com/article/CTX203760/vdi-session-launches-then-disappears & https://support.citrix.com/article/CTX138404/application-connection-starts-but-disappears-after-timeout since might impact negatively the production, plus, there is no official Citrix answer about the registries fixing the "user connection failure" issue.
7 years later and they have not resolve this issue yet ...

Hello,
I solved my problem.
I have installed both components of the citrix profile manager and it works.Hello, which are the components that I need to install on my VDAs for Citrix Profile Manager to work?
User Connection Failure on specific VDA
in XenApp 7.x
Posted
Hello fellow engineers,
We are facing an issue where a VDA is generating high number of user connection failure. VDA machine in most cases is random and is not consistent, but when it happens, it brings "chaos" because users are not able to logon, they keep trying and they constantly trying to logon on that affected VDA.
Troubleshoot done so far:
Has anyone face anything similar? Any suggestion will be highly appreciated.

Constantinos
