There is a requirement to prevent machine going into maintenance mode and extending the reboot time due to slow shutdown of machines. In on-prem deployments, this was possible by setting registry key values as mentioned in our on-prem support articles below. 

MaxFailedRegistrationsAllowed <- Prevent machine going into maint mode (https://support.citrix.com/article/CTX137376)

MaxShutdownDelayMin <- Extending reboot time due to slow shutdown of machines <- https://support.citrix.com/article/CTX237058

However, as DDC's are hosted on the cloud, customers have no access to make these changes. 

In order to set these, values, you will need to install the Citrix Posh SDK on a machine (that has no major Citrix components such as cloud connecter, etc.) . 

Once installed, open Powerhsell and run the below commands: 

Add-PSSnapin Citrix* - This will load Citrix Modules.

Get-XDAuthentication - This will prompt a login box which you will authenticate to your cloud portal. 

Once authenticated, please run the below command to set "MaxFailedRegistrationsAllowed":

Set-BrokerServiceConfigurationData HostingManagement.MaxFailedRegistrationsAllowed  -SettingValue "NumberValue"

To set MaxShutdownDelayMin, you will need to run the below command

Set-BrokerServiceConfigurationData RebootSchedule.MaxShutdownDelayMin -SettingValue "NumberValue"

The default values for these settings are:
HostingManagement.MaxRegistrationDelayMin : 20 minutes
RebootSchedule.MaxShutdownDelayMin : 10 minutes

So if you want to change these value, use the above commands and just replace "NumberValue" with the number you want. 

See below fro example: 


Set-BrokerServiceConfigurationData HostingManagement.MaxFailedRegistrationsAllowed  -SettingValue 20

Problem Cause

DDC's are hosted on the cloud so users will not be able to access them so you will need to change the values via Posh SDK.
