Hi experts

I have a strange problem in a Citrix implementation. Suddenly in one catalog all the machines lose the domain trust relationship at the same time. I can log on as a local admin and reset the machine account password, but after a server restart, all changes are discarded. If I rejoin the xenapp server to the domain, after the restart, the server show that is in the domain but the trust relationship problem is still there. If I disjoin the server from domain, after the restart the server still shows that is joined to the domain.  If i log on as a local admin, create a file/folder in the system drive and restart, the file/folder is missing. If I attach the disk of the xenapp server to another virtual machine, I can create files and folders and the changes are persistent.The catalog is "Server OS" type, and I think this is a citrix related issue, but I´m not sure 100%.

Googling about xenapp servers that lose trust relationship I can only find info about how to reset the machine account password in domain, but I´m looking for a procedure to avoid this situation.

The virtualization is vmware.

Any ideas ?

Thanks in advance and apologies for the bad english

Hi EE,

This question is an inverse of what is usually asked in EE; I am looking for an explanation for what happened not a solution.

The setup:

A web application that used IIS as it's web server was having performance issues (12-27 second load times) when loading a large amount of form data.  The issue only occurred with users on our Citrix environment anyone who accessed the web application from their local desktop didn't have the issue. So while waiting for our Citrix guys to look into the issue, I thought I do a mid-week index rebuild on all tables in the server using the following script:

DECLARE @fillfactor INT
SET @fillfactor = 100
SELECT OBJECT_SCHEMA_NAME([object_id])+'.'+name AS TableName
FROM sys.tables
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
SET @sql = 'ALTER INDEX ALL ON ' + @TableName + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
EXEC (@sql)
FETCH NEXT FROM TableCursor INTO @TableName
CLOSE TableCursor

Open in new window

Observing the fragmentation levels of the tables in the respective database was minor ranging between 7%-13% percent. Suddenly performance issues disappeared for the Citrix users.

How did this happen or did something else to fix this issue that isn't SQL related.

Any assistance is welcome.

Thank you.
Running ldp.exe on domain controller using domain admin credentials and simple bind, I got the same error the first run. Now it gives me The token supplied to the function is invalid.

Running ldp.exe on a different domain controller on different domain/forest, the results are valid.

So something wrong on first domain controller. How/Where to find the problem?

I have about 50 free lancers that I use for specific work. My client system requires that all of the free lancers come from a static IP or IP's. Each of the free lancers use an application that connects back to my client. Is there any way to do this other than deploy citrix or TS desktops for each of the users? I have seen some VPN services but they don't take into account the client application they work fine for internet access. Thanks.
Dear Experts

We have a requirement to store the confidential documents like legal and other customer documents and access it,
we have teams and each team is headed by functional heads and all the users are using their desktop/laptops
At present challenges:
1.Data(document) is not stored in central repository and not access control driven,  all files are exchanged through email back and forth and multiple versions
2.Employee stores his/her data in their own laptops/desktop and functional heads have to depend on users to share it, it has become user mercy or available to share the required document to the reporting manager.
We are looking for the solution where security is strong and also collaboration.
Please suggest the best suited one of I found is Citrix Share file and go with hybrid setup, I request please share the best available solutions, thanks in advance.

We don't to make our network engineer go through all of the work switching ADFS proxy over to the Netscaler if will not work with Duo. Wanted to check to see if anyone here has or is doing this?

Dear EE,

We have two servers.

1) Citrix XenApp 6.5.
2) Database Server MS SQL 2008 R2.

We need to publish SSMS (SQL SERVER MANAGEMENT STUDIO) on our Citrix Xen App 6.5. Please tell me is it POSSIBLE or NOT.

If possible please confirm HOW we can do that thanks.

Unable to connect to one of the XenApp 5.1 servers as it is showing following error. All other servers running in the Farm are working fine.

Network or dial-up problems are preventing communication with Citrix XenApp server.
If the problem persists, please contact your network administrator.

Need your help to resolve this issue.

Hello we have an IIS hosted website, binded to Citrix XenApp Store Front.  We have an AD server, Web Server, Citrix Server.
Currently in order to access site users need a CAC/PKI once this have authenticated they must enter a username & password to get into store front to see their application(s).  What we would like to do is get rid of the username & password, have just CAC/PKI authentication.

Please I need a script (powershell or other) to disconnect all users are using one application on citrix xenapp 6.5.

Best regards,
I have a weird behavior with one user's MS WORD not saving the windows size or location after adjusting.  Once you close the application and reopen it, the application is right back to where it was when it was first opened.  

The system is a Citrix VDI XenDesktop running on a WYSE Zenith zero client OS.
Hi All,

I know this is not supported but, Is there any way to configure WebInterface 5.4 to XenApp 7? If so, Do I need to install StoreFront? How does the XenApp Studio linked to WebInterface? Basically, we would like to use WebInterface just because we need to use the Secure Access - Network Translation feature which is not longer seen in StoreFront.

How do I get user report logs from XenDesktop 7.x? There doesn't appear to be a reporting tools in Studio or Director. Would this be available from the Netscaler? Please advise. Thanks
We have two offices A and B, with a Buffalo NAS in Office B. We have two ways of connecting to the NAS: via fat client and via Citrix. Via fat client we can all connect to the file shares on the NAS. Via Citrix there is no more access within Windows Explorer to the NAS all the sudden. However I can ping it, trace it and it resolves. Office B, with the NAS, is behind a firewall, but I was told all traffic is being passed through, so it doesn't filter Citrix traffic. How come that Citrix traffic (which originates in Office A) cannot connect to the NAS anymore? It used to work before. Has anyone had that issue before? Does the Citrix Client have specific Settings I have to check? Other file Shares DO connect to Citrix Clients, it is only that certain one that is giving me trouble.
I can't find any hints in user groups or Citrix documentation. Any help would be greatly appreciated!

Recently, we move all our servers from on prem to datacenter. Our VDI in a box was running with two hyerV host. Once the move was completed there were some issue with the order reboot with SAN.

After reboot one of the host connection was fixed but second got removed out of grid and now running it maintenance mode. The hyperV host conf between first and second host is the same. The only difference is the on one host VDI manager VHD is deployed on C drive of host and other one with issue has VHD on D drive. But that should not matter when VMs are successfully getting created on D drive mapped from nimble SAN. I even try to reset and run wizard again but I get stuck at grayed out datastore again. Permission on drive and folders are same and the error on trying to reconfigure was as follows and pretty much same on after reset and wizard -

Environment: 2008R2 Windows Print Server (domain connected)
Application: Notepad (delivered by Citrix XenApp 7.6) for test
Endpoint: Various HP laptops & Surface Pro laptops

I have an issue where a user's (and also my test AD account) AD account is unable to install a network printer for the user.


User launches the notepad application, via Citrix; all good so far. Then after attempting to print by clicking file>print, the user clicks Find Printer. A list of printers comes up, and the user finds her printer. After double-clicking to add the printer it displays 'connecting', then 'installing'. Immediately after this, a box with a red X in the left-side appears. It reads: Connect to Printer: 'Windows cannot connect to the printer. Access is denied'

What I've done:

- I was able to reproduce this with an AD account I test with
- Tried manually entering the print server name with printer share name: same result
- Going to explorer (published from Citrix) to put in the full unc path of the printer: same result
- Gave permissions (full) to test AD account on the printer server object in Print MGMT console (on the print server): same result
- Full permissions on the printer object itself: same result
- Full permissions on the printer server itself: same result
- Added to print operations group (local): same result

Thanks in advance,

We are experiencing a very strange phenomenon with our Xenapp environment.
On one of our Delivery groups, when users disconnect their session due to computer standby, network interruption or an unforceen power failure, when they reconnect, the citrix application shows up completely black.
Only way to save there data is to shadow their session and save it myself (yes i can see during a shadow), then terminate the session, wait for 15 seconds and relaunch an application. Then the user is perfectly able to see everything correctly.

The Xenapp environment is build from zero with 2 Netscalers, connecting to 2 Storefront servers, distributing to several Xenapp servers, running windows 2012R2 with Office 2016 installed, (Xenapp 7.12)

In my humble opinion, it is not netscaler or storefront related, as other delivery groups do not have this issue.

To see if it is delivery group related, i created a new delivery group with brand new Windows 2012R2 (fully patched) servers running only Office 2016 and the problem persists.

Does anyone have an idea on what the reason for these black screens are and how we could solve this issue???
Our company s IT is supported by an outsourced vendor. Looks like they are exaggerating the situation. Do we need to follow their recommendation?- see below

We are running on Citrix Xenapp 78 with MS Office Outlook 2016 clients. I have over a hundred users with no issue. One user has fully functional client except that she cannot search the mailbox. It runs but returns no results.
This happens using OWA also.

I am thinking she needs her data re-indexed but do n ot know how to do this.

thank you
As of Quickbooks 2017 R5 and Quickbooks 2018 I am getting a licensing issue in XenDesktop

Citrix says its a 3rd party application issue
Quickbooks says they don't support Citrix

We have been using Quickbooks in XenDesktop for years just recently having issues.

what i have figured out so far
installing all additional packageds with the quickbooks 2018 installation doesn't affect the licensing service.

once quickbooks is installed

A netstat will show the following missing

picaSvc2.exe  1494
picaSvc2.exe 2598

Event viewer doesn't show any errors

citrix event viewer shows license not available when users attempt to login
if you use rdp instead of citrix your able to function fine.
Hi all,

I have prio question regarding a setup which is ongoing;
Thanks for contribution.

- Customer has an existing Office365 environment, currently only email services are in use
- E-Mail should stay in the cloud  @Office365
- There's now an existing on premise AD with users for a Citrix infrastructure, already built and ready for use
- Customer still want's to be able to login to cloud to change the password, same as on the local on premise Citrix environment
(password sync and write back, both)
- So there are 2 "domains", one on premise, one in the cloud

- User should use the on premise logins with outlook / exchange from the cloud
- Link the environemnts via Sync the on premise to the cloud, or migrate to a single environment

Way forward:
I'm looking forward to sync the on premise ad to the cloud with AzureAD connect.
Am I right, that i would have 2 ADS afterwards? How can I combine that scenario?
There are around 20 users - so can be handled manually if required.

Is there annother approach required?
- E.g. Sync on premise via azuread connect and migrate the mailboxes to the new synced environment

Thanks for clarification and hints,

Regards Teggra
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

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.

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?
