Some Notes on the Machines

Try this:

netdom query fsmo

Always nice for recoverability in case of.

GUI on Server 2012:

Powershell:

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

In one swell foop, sync your AD to other domain controllers and Azure. Paste this into administrative Powershell, on the domain controller which does your Azure sync:

repadmin /syncall /AdeP
Import-Module ADSync
Start-ADSyncSyncCycle -PolicyType Initial

And here is the same command set, suitable for a batch file to be run as administrator:

repadmin /syncall /AdeP
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command ^
"Import-Module ADSync; Start-ADSyncSyncCycle -PolicyType Initial"

This command, run from one domain controller, replicates to all of the others set up for this:

repadmin /syncall /AdeP

This is excellent, GUI:

Here’s how to set it for all users in xyz.local:

Get-ADUser -Filter * -SearchBase "OU=Main,DC=xyz,DC=local" | Set-ADUser –scriptPath

and how to clear it for all users in xyz.local:

Get-ADUser -Filter * -SearchBase "OU=Main,DC=xyz,DC=local" | Set-ADUser -Clear scriptPath

This works well:

import-module activedirectory
get-aduser -filter * | set-aduser -scriptpath filename_in_netlogon.vbs

Run the following within Active Directory Module for Windows PowerShell:

Get-ADobject -LDAPFilter "objectClass=organizationalUnit" -SearchBase "DC=domainname,DC=local" | Set-adobject -ProtectedFromAccidentalDeletion $true

Here’s a great set of steps for these:

The short of it is:

1. Bring up the Syncronization Service Manager (“Synchronization Service” in Windows search),
2. Click on Connectors,
3. Click on “Active Directory Domain Services”,
4. Click Run in the right pane, choose Full Synchronization, click OK, and wait for completion to be reported (it’s fairly obvious),
5. Click Run in the right pane, choose Full Import, click OK, and wait for completion to be reported,
6. Click Windows Azure Active Directory,
7. and do the same two Runs as for the other line item.
