I need to clear the logs on my Xenserver running OS 6.5. Not being a linux guru, how do I get this done? Thanks
What does it mean to be "Always On"?
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

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, which we set as the home page.

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

We are looking for a free solution to re-use old PC as thin client without disks. these PCs are going to boot from PXE to point this thin client to Citrix Receiver or Vmware Horizon

Please need your support

Thank you

We are currently running VS Team Explorer 2017 (Version 15.2) in a Citrix environment.  This is running on 2012r2.  We have multiple users that run the system and a few are seeing issues with the application crashing within about 30 seconds after starting up.  It does not appear to be the application directly, but maybe something related to it.  The application actually starts, and if you click fast enough you can actually do things, but after about 30 seconds or so, we get a crash and it closes.

This does not effect all users, just a few.  We have tried resetting their Visual studio parts in the Registry, and Appdata folders, as well as even taking it as far as resetting their profile.  

In the logs I get a .NET crash, and then the Application Error.

Application: devenv.exe

Hi Team,

We are planning to implement Symantec DLP endpoint in our network which includes Windows, Citrix HSDs and Citrix VDIs.

Could you advise how the endpoint agents need to be installed on the hosts/clients in the Citrix environment?
Also, I am not able to see a Symantec article which details about the supporting Citrix versions, can you shed some light on this please?


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.
HI Expert
usually i issue these commands manually
i want script to issue in order to cover this task
can you write a simple script for me to cover this two steps

1- change the path of your working directory!!!!!
 cd c:\program files (x86)\Citrix\Licensing\LS

2- execute this command in order to delete all occupied licenses.
for /f "tokens=1,2" %i in ('udadmin -list ^| find /i "_ud"') do @udadmin -f %j -user %i -delete

3- exit and finish

thank you in advance
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 need a batch file script to execute from a citrix.  We need to publish 10 Websites in single page. User will select and click the website they want to use.  We used for Menu.hta and loading sites file into Menu.

Application Websites are hosted in  Windows 2008 R2 Server and the same published through IE via Citrix Xen App. It tooks around 80 Secs to load starting page once it opened response is good. But our users start complaining about the slowness of startup webpage. Can someone assist me on this plz..

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 ?

What is Citrix recommended reboot schedule for Delivery controllers ?
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.

We don't use the Universal printer driver!
I have some old citrix servers (win 2008R2 std) where all the drivers where loaded; in fact there was no printing policy in place at one point and all the drivers were autocreated!
We built some new servers (win 2008 R2 std) and now and we set a new policy to block autocreated drivers and also added a policy to to map the default printer too in the Citrix session.
I used XPDM (Xenapp Printer Driver Manager) to replicate the drivers to all the servers (from the old ones to the new built ones).
I still have some AX user that cannot see the printers or see them but cannot print when connected to one of the new built servers?!!!
Now when I point any of those users to one of the old Citrix servers he can print successfully!
I even replicated all the drivers i found on one of the old server that print successfully to a new server and still have printing  issues!
What is the problem???
Could it be possible that this tool shows the replication done but in fact it is not?
I haven't tried to install the driver manually on one of the new machines to verify that, but that would be a good test i guess to install it manually after it has been replicated and see if that works!
Thanks for your help.
Hi  expert

I keep getting this errors "User not found"  after i created the account and assign the correct password  and profiles.

Need help for the followng

I am connecting to work pc using Citrix Receiver, just updated to 4.9, hoping it will fix my issue, but no...

So, here is my issue...

I have 2 monitors
I login to my web sites XenDesktop app (not sure what it is)
After login, I download an ica file which I open it with Citrix Receiver...
It is full screen and spans multiple monitors...
The issue starts here... After that I remote desktop to my pc in the system room which is full screen...
But this one uses one monitor, and my other monitor stays black all the time :)

I want to use my other monitor, while I am working, like using browser or watching tv :) whatever...

But I cannot... Citrix spans my 2 monitors, and Remote Desktop uses one off them...

Now, how can I disable this multi monitor spanning?

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

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
