EUC Engineer Cheat Sheet (DRAFT) by

Essentials of EUC Engineer role

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Intune

Overview
- Intune (part of Microsoft Endpoint Manager or MEM) is the centra­lized cloud solution for Unified Endpoint Management (UEM).
 
- It enables admini­str­ators to remotely manage device config­uration and security settings.
 
- Troubl­esh­ooting complex issues, such as applic­ation blocks or compliance failures, typically begins in the Troubl­esh­ooting + support page of the MEM admin center.
 
- This page is used to validate policy assign­ments and user licensing
Interview Prep:
Situation:
An Autopilot enrollment failed for a user stuck at the Enrollment Status Page (ESP), indicating a required applic­ation or policy deployment had timed out.
Task:
I needed to quickly diagnose the cause of the failure using centra­lized tools and ensure the user was licensed and receiving the necessary security config­ura­tions.
Action:
I navigated to the Troubl­esh­ooting + support blade, confirmed the user held an Intune license, and reviewed the Device resource reports to identify the specific failed Config­uration profile assign­ment.
Result
By remedi­ating the identified policy failure and monitoring the device status, the ESP succes­sfully completed, allowing the user to reach a fully configured and secured desktop.

Active Directory

Overview:
- Active Directory (AD) is an extensible directory service providing centra­lized management of network resources
 
- It utilizes logical components like Domains and Organi­zat­ional Units (OUs) to structure the directory.
 
- Certain critical, single­-master operations (FSMO roles) must be carefully controlled on author­itative domain contro­llers.
 
- Examples of FSMO roles include the Schema master (for making schema changes) and the PDC emulator (respo­nsible for processing and replic­ating password changes).
Interview Prep:
Situation
The Schema master role holder was failing due to disk corrup­tion, jeopar­dizing the integrity of the directory schema and preventing necessary modifi­cat­ions.
Task
I needed to quickly perform a forcible seizure of the Schema master role to a standby domain controller to restore the ability to make forest­-wide schema changes.
Action
I used the NTDSUTIL comman­d-line utility to seize the Schema master role onto a prepared domain contro­ller, bypassing the standard transfer process due to the failure of the original server.
Result
The critical single­-master operation was immedi­ately restored on a new domain contro­ller, ensuring the integrity and functi­onality of the directory schema across the forest.
 

Citrix

Overview
- In virtual desktop enviro­nments (like those managed by Citrix), perfor­mance optimi­zation tools are needed to achieve high user density and fast logon times.
 
- Ivanti Enviro­nment Manager (EM) is frequently used, employing a unique multi-­thr­eaded engine that delivers fast logon times.
 
- EM provides granular, contextual policy control and person­ali­zation.
 
- This dynamic policy delivery is more precise and generally faster than relying solely on tradit­ional Microsoft Group Policy Objects (GPOs)
Interview Prep
Situation:
Users in a XenApp session host farm experi­enced erratic desktop person­ali­zation and slow applic­ation start times because tradit­ional GPOs lacked the necessary granul­arity and context awareness.
Task:
I was required to implement Ivanti Enviro­nment Manager to deliver a consis­tent, person­alized desktop experience with fine-g­rained contextual control, thereby accele­rating logon times.
Action:
I configured EM to decouple the user's settings and applied contextual policy based on factors like user group member­ship, leveraging its dynamic policy engine instead of slower, sequential GPO proces­sing.
*Result:
The implem­ent­ation resulted in faster possible logon times and ensured that users maintained the same person­alized desktop experience as they moved between different session hosts.

Laptop building process to Windows 11

Overview
- The modern deployment process uses Windows Autopilot for corporate laptops running Windows 11rn process for deploying corporate laptops to Windows 11 uses Windows Autopilot, which pre-re­gisters the device hash and automates the Out-of-box experience (OOBE) into MEM manage­ment.
 
- Autopilot pre-re­gisters the device hash and automates the Out-of-box experience (OOBE) into MEM management
 
- The Enrolment Status Page (ESP) is a critical phase that delays desktop access.
 
- This delay ensures that essential security settings, such as those meeting Cyber Essentials requir­ements, are succes­sfully applied before the user gains control
Interview Prep:
Situation:
During the deployment of a new batch of Windows 11 laptops via Autopilot, we needed to ensure all devices met the Secure Config­uration criteria of Cyber Essentials immedi­ately.
Task:
The specific requir­ement was to enforce the mandatory use of device unlocking creden­tials, requiring a minimum PIN length of at least 6 charac­ters.
Action:
I used Intune's Compliance Policy or a Device Restri­ction Profile to enforce the minimum length requir­ement for device unlocking creden­tials, targeting the Windows 11 device group.
Result:
The policy succes­sfully applied during the ESP, ensuring all new devices automa­tically enforced the strong device access control required to meet the necessary security baseline upon first user login.
