Unable to Remove XenDesktop Delivery Controllers from the XenDesktop Site

From http://support.citrix.com/article/CTX139505

Solution

Complete the steps to remove the orphaned Delivery Controller (Controller) from a XenDesktop 7.x site:

1. Run the Get-BrokerController command from PowerShell to get the SID of the orphaned Controller.
   
   
2. Execute the following PowerShell script, replacing the XenDesktopDatabase with your XenDesktop database and the DCSID with your SID of the Controller you want to remove:
   

$DBName = "XenDesktopDatabase"
$EvictedSID = "DCSID"

#
# Generate Database 'Evict' Scripts for XenDesktop DataStore
#
#
Get-ConfigServiceStatus

Get-LogSite 

Get-BrokerController   -Filter {(SID -eq $EvictedSID)} -MaxRecordCount 2147483647

Add-Content "$PWD\evict_$sid.txt" (Get-AcctDBSchema  -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-HypDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-ProvDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-BrokerDBSchema -DatabaseName $DBName -ScriptType 'Evict' -SID $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-MonitorDBSchema -DatabaseName $DBName -DataStore 'Site' -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-SfDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-EnvTestDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-ConfigDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-LogDBSchema -DatabaseName $DBName -DataStore 'Site' -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-AdminDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

Add-Content "$PWD\evict_$sid.txt" (Get-AnalyticsDBSchema -DatabaseName $DBName -ScriptType 'Evict' -Sid $EvictedSID)

# Script completed successfully

# Generate Database 'Evict' Scripts for 'Logging' DataStore

#
Get-ConfigServiceStatus 

Get-LogSite 

Get-BrokerController   -Filter {(SID -eq $EvictedSID)} -MaxRecordCount 2147483647

Add-Content "$PWD\evict_$sid.txt" (Get-LogDBSchema -DatabaseName $DBName -DataStore 'Logging' -ScriptType 'Evict' -Sid $EvictedSID)

# Script completed successfully

# Generate Database 'Evict' Scripts for 'Monitor' DataStore

#
#
Get-ConfigServiceStatus 

Get-LogSite 

Get-BrokerController   -Filter {(SID -eq $EvictedSID)} -MaxRecordCount 2147483647

Add-Content "$PWD\evict_$sid.txt" (Get-MonitorDBSchema -DatabaseName $DBName -DataStore 'Monitor' -ScriptType 'Evict' -Sid $EvictedSID)

# Script completed successfully

After running the script, the evict.txt file is created under the users profile. The file contains a script required to run on the SQL server.

Problem Cause

The XenDesktop 7.x Delivery Controllers had been removed from Active Directory (AD) before they were removed from the XenDesktop site. The Controller removal process makes use of stored procedures that require a valid domain SID to generate the Transact-SQL (T-SQL) eviction script.
When a Controller is removed from AD before attempting to remove it from Studio, the stored procedure fails to generate the necessary part of the T-SQL script that removes the references to the Controller.
