Handy Citrix Tips

Stuck session - if session cannot be logged off and does not show on the server you can log off the session in powershell:

  • add-pssnapin *citrix*
  • Get-BrokerSession -username Domain\User | Set-BrokerSession -Hidden $true

Find location of the citrix database used by delivery controllers and netscaler:

  • Get-Brokerdbconnection


Remove citrix licence from account to free up for another user

On the citrix controller:

  • cd "C:\Program Files (x86)\Citrix\Licensing\ls"
  • Udadmin -list -times
  • udadmin -f XDT_ENT_UD -user <username@domain> -delete (example udadmin -f xdt_adv_ud -user <username@domain> -delete)

You might have to repalce the license type with

  • XDT_ADV_UD XenDesktop Advanced
  • XDT_PLT_UD Citrix Virtual Apps and Desktop Premium

Show settings for citrix motoring logging:

  • asnp Citrix.*
  • Get-MonitorConfiguration
  • Set-MonitorConfiguration -<setting name> <value>

Citrix Troubleshooting

If there are no apps available in the storefront check the citrix database for connection - look at the netscaler and see if there are any connection errors showing on console.


For errors when connecting from a new environment check that ports 8080, 1494, 80, 2598, 443 are open between client and all xenapp servers and netscaler.

Citrix RDP to VDA

To RDP to citrix VDA user needs to be admin or member of the remote desktop users group. They will also need to be a member of the Airect Access users which is determined by this registry value: HKLM\Software\Citrix\PortICA\DirectAccessUsers

This will give you an SID, use this to find the group it references in AD

$SID = "<enter SID here>" ; Get-ADObject -Filter * -Properties * | where{$_.objectSid -eq $SID}

Duplicate entries in citrix controller

Method to delete Stale entries from citrix database

Step 1) To find the machine ID in Citrix Monitoring DB

Select ID,Name,IPAddress,HostingServerName,CurrentRegistrationState From [MonitorData].[Machine] where Name Like'%VDA03%'

Select ID,Name,IPAddress,HostingServerName,CurrentRegistrationState From [MonitorData].[Machine] where Name Like'%VDA06%'

Select ID,Name,IPAddress,HostingServerName,CurrentRegistrationState From [MonitorData].[Machine] where Name Like'%VDA09%'

step 2  : To compare the Machine ID in Session Table 

select * from [MonitorData].[Session] where  MachineId = '1E22A7A8-AD67-46B9-AB87-EACE0DF22AE3'   ---  VDA03

select * from [MonitorData].[Session] where MachineId = 'FCC1D88F-D553-4C96-AA92-5D3A7435D846' --- VDA06

select * from [MonitorData].[Session] where MachineId = '71889325-37B1-4929-B527-D81BA04ABC6D' ----VDA09


Step 3 : Then replaced ID of stale Machine Id with the correct Machine Id in the Session Table 

----- VDA03

UPDATE [MonitorData].[Session] SET MachineId='DB76C220-48BE-4297-95BA-D105109E735A' WHERE MachineId='1E22A7A8-AD67-46B9-AB87-EACE0DF22AE3' 

----- VDA06

UPDATE [MonitorData].[Session] SET MachineId='1AD3F50D-97E2-4660-8656-1523AED50D83' WHERE MachineId='FCC1D88F-D553-4C96-AA92-5D3A7435D846' 

----- VDA09

UPDATE [MonitorData].[Session] SET MachineId='207FC7C2-FF72-4DEA-8F30-A5B3FD8CC410' WHERE MachineId='71889325-37B1-4929-B527-D81BA04ABC6D'


Step 4 : Removed the Old Stale Machine as per the following

DELETE FROM [MonitorData].[Machine] WHERE ID = ‘1E22A7A8-AD67-46B9-AB87-EACE0DF22AE3’

DELETE FROM [MonitorData].[Machine] WHERE ID = ‘FCC1D88F-D553-4C96-AA92-5D3A7435D846'

DELETE FROM [MonitorData].[Machine] WHERE ID = ‘71889325-37B1-4929-B527-D81BA04ABC6D'

Clear and recreate database

Completethe following to repair the citrix local host database.

Carry this out on the server containing the citrix database

1. Download PsExec Sysinternal tool on the Delivery Controller, copy to C:\Temp

a. PsExec: https://docs.microsoft.com/en-us/sysinternals/downloads/psexec

2. Stop Citrix High Availability Service

3. Open the command prompt, navigate to C:\Temp, execute the below command to elevate the command prompt with Network Service account

a. PsExec -i -u "NT AUTHORITY\NETWORK SERVICE" cmd

4. Run the command whoami to confirm the account.

5. Navigate to the SqlLocalDB installed path

a. For SQL LocalDB 2014: cd "C:\Program Files\Microsoft SQL Server\120\Tools\Binn"

For SQL LocalDB 2017: cd "C:\Program Files\Microsoft SQL Server\140\Tools\Binn"

6. Execute the below two commands to Stop and delete CitrixHA (LocalDB) database.

a. SqlLocalDB stop CitrixHA

b. SqlLocalDB delete CitrixHA

7. Remove the below files located in C:\Windows\ServiceProfiles\NetworkService

a. HADatabaseName.*

b. HADatabaseName_log.*

c. HAImportDatabaseName.* (If exists)

d. HAImportDatabaseName_log.* (If exists)

8. Start Citrix High Availability Service

9. Execute the below command to confirm that CitrixHA is recreated

a. SqlLocalDB i

CitrixHA <<<< disappears just after Stop/delete in step 5, and appears after start Citrix High Availability Service in step 7 MSSQLLocalDB


PVS

issue with PVS server unable to load Citrix.PVS.Snapin could be caused by recent upgrade of PVS/citrix or applayering. You will need to redeploy and reregister the plugin. Use the following commands:

  • CD \Windows\Microsoft.NET\Framework64\v4.0.30319
    • .\InstallUtil.exe "C:\Program Files\Citrix\Provisioning Services Console\Citrix.PVS.Snapin.dll"
  • CD \Windows\Microsoft.NET\Framework\v4.0.30319
    • .\InstallUtil.exe "C:\Program Files\Citrix\Provisioning Services Console\Citrix.PVS.Snapin.dll"

PVS replication of images is done through RoboCopy.

See .bat settings:

  • Robocopy <Location of new + current builds> <Network location of other PVS builds in cluster> *.vhdx *.vhd *.avhd *.avhdx *.pvp /b /mir /r:5 /w:5 /xf *.lok /xd WriteCache /xo

Issue with PVS citrix xenapp servers with performance and possible crashing of environment:

Issue could be due to write cache disk not being online during boot of citrix server causing write cache to default to the PVS server.

Solution is to set disk management to online all disks on boot in PVS image:

  • diskpart
  • sanpolicy=onlineall
  • exit

If disk still shows offline due to policy set by administrator then the following attribute will need to be set on the disk:

  • diskpart select disk <disknumber>
  • attributes disk (check to see if its read only)
  • attributes disk clear readonly

May also need to assign the same unique ID to the disk as the gold image:

Find unique id in diskpart:

  • Uniqueid disk

Change unique disk id to match

  • Unique disk id=<diskid>

Citrix profile management - troubleshooting

When seeing issues with citrix UPM profiles use the config checker to identify any potential issues:
