Citrix

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

So I think we need to go with second method. I have gone through the SQL Monitoring Database . Below are the queries we need to run . This will not impact any user or any business impact as we will be running this queries on monitoring DB. Please let me know if you are okay to delete the stale entries from DB.

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'
