Live Documentation Fetching

Use the WebFetch tool to retrieve live content from reference URLs for accuracy. Microsoft documentation is frequently updated.

When to Fetch

Scenario	Action
PowerShell cmdlet syntax	Fetch https://learn.microsoft.com/en-us/powershell/module/configurationmanager/{cmdlet-name}
Troubleshooting steps	Fetch https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/ + topic path
Version-specific features	Fetch What's New page to confirm availability
SQL view schemas	Fetch SQL view docs for accurate column names and joins
Task sequence steps	Fetch step documentation for current options and variables
Error codes	Fetch troubleshooting docs for specific error resolution

Fetch Guidelines

1. Always fetch for cmdlet syntax — parameters change between versions
2. Fetch for troubleshooting — resolution steps may be updated
3. Verify version requirements — confirm which ConfigMgr version supports a feature before recommending
4. Cross-reference error codes — fetch specific error code documentation
5. Cache awareness — skip re-fetching URLs already retrieved in the same session

Reference Files

Load the appropriate reference file based on the user's topic:

Topic	Reference File	Covers
Patch management, WSUS, ADRs	software-updates.md	SUP config, ADRs, WSUS maintenance, update logs
App deployment and packaging	application-management.md	App model, detection methods, deployment, app logs
OS deployment, task sequences, drivers	osd.md	Task sequences, boot images, variables, driver management, OSD logs
Collections and WQL queries	collections.md	Membership rules, WQL queries, collection evaluation
PowerShell automation	powershell.md	Module setup, common cmdlets, client actions
Client issues and log files	troubleshooting.md	Client health, common issues, log file reference
SSRS reports, SQL views, CMPivot	reporting-sql.md	Built-in reports, SQL view categories, sample queries
SQL Server tuning for MECM	sql-best-practices.md	MaxDOP, memory, tempdb, maintenance plans, RCSI, AG, diagnostics

Scripts

All scripts write CMTrace-compatible logs. Open the resulting .log files with CMTrace for color-coded filtering.

Script	Purpose
Import-CMModule.ps1	Fault-tolerant ConfigurationManager module loader. Use: . .\scripts\Import-CMModule.ps1 -SiteCode "PS1"
Invoke-CMClientHealthCheck.ps1	Read-only health check for a ConfigMgr client. Validates services, WMI, policy, inventory, cache, MP connectivity, disk, pending reboot. Log: C:\Windows\CCM\Logs\ClientHealthCheck.log
Repair-WMISafely.ps1	Non-destructive WMI repair. Uses winmgmt /salvagerepository (NOT /resetrepository), re-registers WMI DLLs, recompiles critical MOFs. Log: C:\Windows\Logs\WMIRepair.log
Invoke-CMServerHealthCheck.ps1	Read-only health check for a ConfigMgr site server. Validates SMS services, SMS Provider, site component status, inbox backlogs, disk space, SQL connectivity, recent event log errors. Log: C:\Windows\Logs\CMServerHealthCheck.log

Core Concepts

Configuration Manager Hierarchy

Reference: Design a hierarchy of sites

• Central Administration Site (CAS): Top-level site for multi-site hierarchies (optional)
• Primary Site: Main administration point, hosts the database
• Secondary Site: Child of primary site, distributes content to remote locations

Key Site System Roles

Reference: Site system roles

• Management Point (MP): Primary client-to-site communication
• Distribution Point (DP): Content storage and distribution
• Software Update Point (SUP): WSUS integration for patch management
• State Migration Point: User state storage during OSD
• Reporting Services Point: SSRS integration

Best Practices

Reference: Site and site system prerequisites

1. Maintenance: Run WSUS cleanup monthly, reindex SUSDB, monitor component status, back up site database
2. Performance: Limit collection incremental updates, distribute content before deployments, use boundary groups effectively
3. Security: Use HTTPS where possible, implement RBAC, use least-privilege service accounts
4. Deployment: Test in pilot collections first, use phased deployments, configure maintenance windows
