Good afternoon,

I've got an issue where I can't get Chrome extensions installed on my image, I put it into write mode, drop the change user/install into the command prompt, install the chrome extensions and it doesn't update them to version 5.

The chrome extension is the legacy browser support

We're on Xenapp 6.5

What's the best way to get chrome extensions updated so they work first time for the users, is there somewhere on the xenapp server I can put them?

I have a client with about 30 users that work at home about 50% of the time.  They continue to have connection issues logging into Citrix, RDS and now a Parallels server.  The problem is not what we are logging in to, which is what they think.  We have the users mostly hardwired to their router so we aren't dealing with wi-fi issues.  There are various internet vendors (Comcast, Verizon, ect) mostly in the DC area but some scattered across the eastern states.  Everyone works fine for awhile (like the last two weeks, barely a problem) but then we have various issues that turn out to be a user working from home, locking a file or getting disconnected repeatedly.  We might have 10 users logging in from DC office to Berkeley without any service disruptions during that same time.  

Before we start ripping servers out, I think we really have to make sure that the WAN is working correctly.  That starts with home internet.   Most of them are running a company provided VOIP phone at home.  It doesn't seem related but maybe it is.
Hello Experts

We just migrated to a new citrix enviroment, and everything has been working fine, except for office.

at random times, office will just shut down with a "out of license" error, not giving the users a chance to save.

We have 20 users online, and we bought  50 EDU license (we are a school).

We logged on to our VLSC and we are barely reaching the limit.

Any ideas why this is happening?
Our server is in Amazon AWS.  Windows Server 2016.  Running Citrix VDA(XenDesktop) 7.13

Basically, Enhanced Securtiy Configuration is disabled on the host, as well as every possible place in Group Policy.  Yet, whenever a new user logs in and runs IE, it says "Internet Explorer Enhanced Security Configuration is enabled", but a refresh, or reload of the browser, and it goes to Google.com, which we set as the home page.

We're removed, re-added policies, and are stuck.

Citrix not able to load applications. We are login but application not able to load?

When I click the application it run for 3 Sec and it disappears.
This is using 5 Xenserver 6.2. All the while, we were using Acronis backup and replication version 11.x. However, this is the outdated version and tends to fail the backup operations. The only way when the backup is failed, we have to uninstall, reboot the system, and then re-install the Acronis  from the scratch. Is kind of frustration. Our management decided not to upgrade to use the current Acronis version 12. In fact, we are out of budget to get any replacement.

I heard that using the Citrix Xenserver XE commands, we can automate the backup operations without down the VM. Please shed the light on how to get this done, and other alternative way.

Thank in advance.

I am cleaning some Citrix / RDS servers and I wonder if it's safe to compress the MSO Cache folder via the NTFS folder property (built-in file system compression) ?

Have you ever done that and is it a risk or does it have an impact for the installed Office ?

We did recently move our Citrix xenapp78 license server to another VM. Only the one server out of 9 others is producing this warning.
What do we need to do to correct or stop the messages. See below)
Note: message indicates pool name "Xenserver01"
 that pool had only the one server in it and we have removed the server from the pool so there is only the VM xenserver01.

I am trying to install the Grammarly plugin on a Citrix server for all users.
This is a Word and Outlook plugin (grammar and spell checker).
The plugin will only install in admin mode but will not install for all users.

The plugin will install itself in

C:\Users\%username%\AppData\Local\\Grammarly\Grammarly for Microsoft Office Suite 

Open in new window

of the admin user account. The .DLL used in Word is the following:

C:\Users\%username%\AppData\Local\Grammarly\Grammarly for Microsoft Office Suite\6.6.116\09D34098D5\GrammarlyShim32.dll

Open in new window

I tried to copy this directory to the same location of a user account.
Then I open word and try to add the .DLL as an addin, but it doesn't work.
No error message, the addin/DLL will just not appear in the list.

I am not an expert with Office plugins, I would like to know if there is a way to activate the plugin for the standard users ?

Were having an issue where, users password are expiring and they are having a diffcult time changing passwords within a citrix environment. Please let me know what others are doing or if there is something that needs to be enabled.

Hi Experts,

We added a new server to our environment and would like citrix to communicate with that server. In the past environments I remember having to configure outside\inside address in the  firewall or the citrix server itself to allow communication between servers.

HI Citrix experts

with old Citrix 6.5  on Citrix APP center, we can send a message for a user or all users

also, we can stop users to log in to a specific server by using

prohibit logins and reconnection for this server

with new Citrix 7.12  the message not working check the attached file

and I don't find where I can stop login to a specific server

kindly advice
I had this question after viewing In Xenapp 7.8 can you turn off the user having to give you permission to shadow them?.

yes i have no problem if user has to accept remote support

but i want to find a way that when the user accept remote support helpdesk guy will get control directly no need to request control

is it possible ?


kindly advice
See this error repeatably  DCOM got error "2148007941" from the computer SERVER-123 when attempting to activate the server:

I am in the US I need to connect to SQL database that is in Canada to pull some data stored there.

I have 3 situations:
1- From my client machine which is in the US i RDP the database server directly (in Canada) launch the application (ArcMap) that is installed there and pull my data --> very fast
2- From my same machine i connect via citrix to the application (Arcmap) that then connects to that database -->very slow
3- From my machine I RDP the Citrix server (In Canada) where the application is installed and the connects to the database (In Canada)-->very slow

I increased the memory on that Citrix server and the problem is still the same!

Any ideas?

We are running 2 Physical machines with 2 x 22 cores processor each, i would like to run 8 VMs on each. Each VM will have 5 core processor. Now my question is how many cores license do i need for each VM(windows server 2016)

Standard 16 cores or I have to license 2 x 22 cores?

Good morning.  I work for a law firm in Los Angeles and am looking for an Citrix expert to testify in a ongoing case.  The issue we need testimony on is that it is common to experience problems printing in a Citrix environment, especially if one is printing outside of the network.  I have read numerous articles and posts that this is indeed true, but I need an expert in Los Angeles to testify to this.  Obviously, experts are paid.  If anyone in this exchange is interested, please contact me by email, stjohns@smithmyerslaw.com.  Thank you.

Hello.  We are experiencing an issue isolated to one user (out of around 400) that has her Citrix session lock up for about 15-20 seconds when either receiving a Calendar notification or a Skype message.  I've tried everything I can think of.  We rebuilt her Citrix profile, updated latest audio drivers, upgraded to Citrix 4.8, etc.  Also worth noting is I delayed her sound via Skype and the delay was reduced to a mere 2-3 seconds.  Has anyone else experienced this issue with Outlook or Skype?  Thank you.
We have two Citrix servers and when we try to print a PDF from one of them it doesn't select the default printer.  We have to manually select which printer to use.

How do I fix this?
Hello, I just set up Citrix SSPR in my XenDesktop environment following these instructions:


And, for whatever reason, it works as long as my Self Service account is a Domain Admin.  But, any other permission set lower than that, and the process fails (I get 'the supplied password is invalid' for PW changes and 'you cannot use account self-service' for unlocks).

I've delegated permission as specified in the guide to the domain (several times), I've even tried making my self service account an Account Operator.  Our domain has pretty stock settings, it's almost brand new, and we haven't tinkered with the OU permissions at all.  Any idea why this account would need to be Domain Admin to work?  What other permissions do I need to grant?


What's the difference between: VMware Horizon and VMware Horizon Mirage ?

My goal is to be able to deploy personalized virtual desktop (VDI solution) so that the users in my company can use it like a Terminal Server but it is deployed from one Golden Image for standardization.

Previously in Citrix world, it is XenDesktop, but in VMware I'm not sure.
VMware ThinApp is the tool/software which can be used to deliver virtualized application running on the Terminal Server like XenApp.

A user will open a pdf file.  Almost immediately after the pdf opens, adobe reader becomes into a not responding state.  When this happens the adobe reader window goes gray.  The user will force close the adobe reader.  While this is happening it does not matter the location of the pdf file.  It can be an attachment in outlook 2010, located on the network or on the persons desktop.  
We had 1 person after a while adobe became response, other user where the block never cleared.

Best GUESS - It seems like adobe is attempting to access the internet, and becomes non-responsive when its internet connection fails.  The user has to authenticate to the proxy to be able access the internet.  We have had the user authenticate to the internet, but still adobe stays non responsive.

What tools could be use to identify why adobe becomes non-responsive in citrix?
When my domain users log into My Citrix servers they are able to see the network icon to see all the servers on the network etc.

I believe I need to create a policy to stop this on the server.

The Citrix servers are Windows Server 2012 virtual servers.
I only want the regular domain users to be restricted.

Where would i go to create this?
