AADSync Performance Counters Error

While working on a project recently, I came across the following error on my AADSync server:

Log Name:      Application
Source:        ADSync
Date:          1/12/2015 12:47:11 PM
Event ID:      6313
Task Category: Server
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      AADSync.contoso.com
Description: The server encountered an unexpected error creating performance counters for management agent “xxxxx.onmicrosoft.com – AAD”.

Performance counters will not be available for this management agent.

To fix this issue in AADSync, you can either perform a clean install (often out of the question) or run the following commands to reload the performance counters:

1. Stop AADSync’s service;
2. Delete the following registry key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ADSync\Performance];
3. Recreate the Performance key;
4. Run the following two commands from an elevated command prompt:
• unlodctr.exe ADSync
• lodctr.exe “C:\Program Files\Microsoft Azure AD Sync\Bin\mmsperf.ini”
5. Start AADSync’s service.

Azure Active Directory Connect Public Preview

The latest version of the Azure AD Connect has been released – the March 2015 Public Preview update.

The Azure AD Connect wizard Public Preview provides a guided experience for integrating one or multiple AD forests with Microsoft Azure AD. Optionally you can configure Exchange Hybrid deployment, password change write-back, ADFS and Web Application Proxy.

Azure AD Connect encompasses functionality that was previously released as DirSync and AADSync. These tools will eventually stop being released individually and all future improvements will be included in updates to Azure AD Connect.

This latest version has been updated with new capabilities, support for additional sync options, Additional Tasks and “Pilot Mode”.

You can download it from the Connect website.
