Instant Summary

This NinjaOne blog post offers a comprehensive basic CMD commands list and deep dive into Windows commands with over 70 essential cmd commands for both beginners and advanced users. It explains practical command prompt commands for file management, directory navigation, network troubleshooting, disk operations, and automation with real examples to improve productivity. Whether you’re learning foundational cmd commands or mastering advanced Windows CLI tools, this guide helps you use the Command Prompt more effectively.

Key Points

  • Confirm Deletion and Choose the Safest Restore Method: Use Get-ADObject -IncludeDeletedObjects to locate deleted users or groups before selecting a restore path.
  • Enable and Verify the AD Recycle Bin: Use PowerShell commands like Enable-ADOptionalFeature -Identity ‘Recycle Bin Feature’ and verify using Get-ADOptionalFeature.
  • Restore Objects Safely and Document the Process: Use Restore-ADObject -Identity to recover deleted users, optionally moving them to a staging OU for validation.
  • Rebuild Linked Attributes and Validate Permissions: Use Get-ADUser -Properties memberOf to confirm group memberships, servicePrincipalName, and ACL integrity; confirm authentication, resource access, and GPO application via gpupdate and gpresult.
  • Check Replication, Hybrid Synchronization Health: Run repadmin /replsummary and repadmin /showrepl across all Domain Controllers to confirm convergence and identify lingering objects.
  • Collect Evidence and Publish Compliance-Ready Reports: Store PowerShell logs, event viewer exports, and before/after LDIFDE files in your documentation system.

Accidental deletions in Active Directory can cause many problems, especially if restores are incomplete or replication is unhealthy. Learning how to perform an Active Directory object restore with minimal risk has a lot of value for MSPs. It protects your data and helps in guaranteeing the health of your cloud directories.

A guide for restoring a deleted AD user

📌 Prerequisites:

  • Domain functional level Windows Server 2008 R2 or higher for the Recycle Bin
  • Recycle Bin enabled (Get-ADOptionalFeature to verify)
  • Healthy replication (repadmin /replsummary) and SYSVOL (dfsrdiag pollad)
  • Administrative credentials on a domain controller or management host
  •  Backup of system state or previous LDIFDE export for authoritative restores
  •  Evidence workspace for PowerShell transcripts and validation outputs

Step 1: Confirm deletion and evaluate restore path

Check if the object is in the Active Directory Recycle Bin through Windows PowerShell with elevated permissions. Use the following command:

Get-ADObject -IncludeDeletedObjects -Filter 'Name -like "user"' 

If you find the object you’re looking for, restore it from the Recycle Bin. For tombstoned or replicated deletions, you won’t be able to restore from the Recycle Bin. You’re going to need to restore from a system state backup.

Step 2: Enable and verify the Recycle Bin if needed

If you don’t have the Recycle Bin enabled for your Active Directory objects, you won’t be able to restore anything from it. Enable using Windows PowerShell with elevated permissions with the following command:

Enable-ADOptionalFeature -Identity 'Recycle Bin Feature' -Scope ForestOrConfigurationSet -Target 'forest.local'

To verify that the Recycle Bin is enabled for your system, use the following command:

Get-ADOptionalFeature

Log the activation details and verification for your evidence file for transparency and so you can keep track of everything in your system.

Step 3: Restore via PowerShell

Once you’ve identified the deleted Active Directory object, you can now restore it using Windows PowerShell with elevated permissions. Use the following command:

Restore-ADObject -Identity "CN=John Doe\0ADEL:GUID,CN=Deleted Objects,DC=domain,DC=com"

You can also use -TargetPath to move it to a staging OU for validation.

Once the object is restored, record the transcript of your PowerShell commands and the associated event IDs in your logs for transparency and as evidence files.

Step 4: Handle linked attributes and group memberships

Once you’ve restored the Active Directory object, you need to ensure that everyone who had access to it continues to have access to it.

To do that, you need to check group memberships and access control lists. Use the following commands:

Get-ADUser -Identity "John Doe" -Properties memberOf 

If there are still missing memberships, restore them manually or via script.

To validate that everyone has access again, use servicePrincipalName, UPN, and logonName fields.

Step 5: Validate replication and lingering objects

After the restore, you need to ensure that everything is back to where it’s supposed to be. Run repadmin /showrepl and repadmin /replsummary on all your Domain Controllers. Check if there are lingering object warnings. Confirm restored attributes appear across partners.

Once that’s done, log the replication status for your records.

Step 6: Check hybrid synchronization (if applicable)

If you’re using Entra Connect, you need to verify that the restored object syncs to the cloud. Monitor DirectorySyncClientCmd.exe or portal status. Handle soft-deleted cloud accounts carefully to avoid duplication.

After you’ve restored the AD object using PowerShell or the Active Directory Recycle Bin, check that the object’s immutable ID (sourceAnchor) and DistinguishedName (DN) remain consistent with its previous sync state.

If the attributes are Inconsistent or changed, this can cause Entra Connect to treat the object as new, leading to duplicate cloud accounts.

You can monitor the sync process by running DirectorySyncClientCmd.exe /status in Command Prompt. You can also open the Microsoft 365 Admin center > Users Active Users and look for the user that you restored. Make sure that:

  • The user appears under Synced with Active Directory
  • There are no synchronization errors
  • The Last Sync time is accurate and updated

Step 7: Run integrity and access checks

After restoring a deleted user account in Active Directory, confirm that the user can successfully authenticate, that their permissions and group memberships match the pre-deletion state, and that relevant Group Policy Objects (GPOs) are being correctly applied. To do that, you should:

  • Have the user log in to their domain-joined workstation to confirm the account is active and not locked or disabled.
  • Use Get-ADUser username -Properties MemberOf | Select-Object -ExpandProperty MemberOf in Windows PowerShell to verify restored group memberships.
  • Use gpupdate /force and gpresult /r to verify that the user and the relevant computer policies are applied.
  • Run repadmin /replsummary and repadmin /showrepl in Command Prompt to confirm that there are no replication errors or stale data.

Step 8: Document and store artifacts

Collect PowerShell transcripts, eventvwr logs (Directory Services and DFSR), LDIFDE export before/after, and screenshots of ADUC showing restored objects. Upload them to your documentation tool so you can keep track of all your actions.

9: Update runbooks and communicate lessons

Note the root cause of why the user was deleted in the first place (UI deletion, script error, sync issue). Once you’ve figured out why it happened, improve protections and set up guard rails so it doesn’t happen again. Keep retention settings documented and upload them to your documentation tool.

Step 10: Publish a monthly evidence packet

Publish a monthly evidence packet to keep executives updated. Include deleted/restored counts, restore paths used, convergence time, linked attribute fixes, hybrid sync validation, and exceptions with owners and expiry.

Share in QBRs or audit reviews. You can also summarize all the data in a one-page document for easy scannability.

FAQs

After restoring an AD object, run the following replication health checks on each Domain Controller:

repadmin /replsummary

repadmin /showrepl

  • repadmin /replsummary will give you a summary of replication success rates and error counts.
  • repadmin /showrepl will show you detailed partner replication status and timestamps.

You can check the Entra Admin Center > Users > Active Users and look for the restored account.

Confirm that the object’s ImmutableID (sourceAnchor) matches the original cloud identity. If the user exists as a soft-deleted account, permanently delete it in Entra ID before re-syncing to avoid duplication.

Once that’s done, you need to trigger a delta sync to finalize reconciliation through the following command in Windows PowerShell:

Start-ADSyncSyncCycle -PolicyType Delta

Document the following details:

  • PowerShell transcripts and event logs (Directory Services, DFSR).
  • LDIFDE exports pre- and post-restore.
  • Screenshots from Active Directory Users and Computers (ADUC) showing restored objects.
  • Replication status outputs (repadmin /replsummary).
  • Synchronization verification, if hybrid

If a restored Active Directory object fails to sync with Microsoft Entra ID (formerly Azure AD), it usually indicates an issue with attribute mismatches, duplicate soft-deleted accounts, or stale connector data. Here’s how you can troubleshoot:

  • Check synchronization logs:Run DirectorySyncClientCmd.exe /status in Command Prompt or open the Synchronization Service Manager (miisclient.exe) to review errors.
  • Confirm ImmutableID alignment:Ensure that the on-prem object’s ImmutableID matches the corresponding cloud user’s sourceAnchor.If mismatched, use PowerShell to reset the link with this command:
    Set-MsolUser -UserPrincipalName “[email protected]” -ImmutableId “Base64EncodedValue”
  • Force a delta sync with this command:
    Start-ADSyncSyncCycle -PolicyType Delta

In Active Directory (AD), deleted objects remain in the directory for a limited time before being permanently removed. This duration is determined by two key lifecycles: the tombstone lifetime and the Recycle Bin retention period (if enabled).

The tombstone object is retained in the Deleted Objects container for the tombstone lifetime, typically for 180 days. If the Active Directory Recycle Bin is enabled, deleted objects remain in a logically deleted (soft-deleted) state for the deleted object lifetime, which typically matches the tombstone lifetime (180 days by default).
