You Should Know: Essential Commands & Steps for Troubleshooting Microsoft Entra ID
1. Diagnosing Sign-In Errors
- Use Azure AD Sign-In Logs (Azure Portal) to track failed logins:
Get-AzureADAuditSignInLogs -Filter "status/errorCode ne 0" -Top 10
- Check conditional access policies blocking users:
Get-AzureADMSConditionalAccessPolicy
2. Resolving Password Issues
- Force password reset via PowerShell:
Set-AzureADUserPassword -ObjectId [email protected] -ForceChangePasswordNextLogin $true
- Check password expiration:
Get-AzureADUser -ObjectId [email protected] | Select PasswordPolicies
3. Fixing MFA Problems
- Disable MFA for a user (temporarily):
Set-MsolUser -UserPrincipalName [email protected] -StrongAuthenticationRequirements @()
- Re-enable MFA:
$mfa = New-Object -TypeName Microsoft.Online.Administration.StrongAuthenticationRequirement Set-MsolUser -UserPrincipalName [email protected] -StrongAuthenticationRequirements $mfa
4. Handling Entra ID Sync Issues
- Force Azure AD Connect sync:
Start-ADSyncSyncCycle -PolicyType Delta
- Check sync errors:
Get-ADSyncAADPasswordSyncErrors
5. Troubleshooting Device Joining Failures
- Check device registration status:
Get-AzureADDevice -All $true | Where-Object { $_.ApproximateLastLogonTimeStamp -lt (Get-Date).AddDays(-30) } - Remove stale devices:
Remove-AzureADDevice -ObjectId <DeviceID>
6. Preventing Brute Force Attacks
- Enable Azure AD Smart Lockout:
Set-AzureADMSAuthenticationMethodPolicy -EnableSmartLockout $true
- Monitor suspicious logins:
Get-AzureADAuditSignInLogs -Filter "riskEventTypes/any(t: t eq 'anonymizedIPAddress')"
7. Fixing Licensing Errors
- Check assigned licenses:
Get-AzureADUserLicenseDetail -ObjectId [email protected]
- Remove conflicting licenses:
Set-AzureADUserLicense -ObjectId [email protected] -RemoveLicenses "SKU_ID"
