Force Active Directory Sync/Replication With All Partners

From time to time I need to force sync all of my GCs aka DCs. This is a quick way to force everyone to replicate. If you have a lot of GCs this could take a while.

 repadmin /replicate destination_dsa Naming Context /allsources
 repadmin /replicate dc=test,dc=com /allsources

Destination server Name:
Naming Context: dc=test,dc=com (Domain partition)

How To Force SharePoint to Sync with Active Directory

Occasionally I have a user that changes their last name (or we got it spelled wrong) and I need the change to reflect across SharePoint (why SP doesn’t do this by itself I have no idea). In order to aid this process I found this script to force a resynchronize of each instance of the user profile in the user information lists. The script accepts one argument, which is the username to resync in the format DOMAN\User. Create a new powershell file with a ps1 extension and paste the code below into it.

$webapps = Get-SPWebApplication
 foreach ($webapp in $webapps) {
 [string] $login = $args[0]
 $sites = get-spsite -Limit All -WebApplication $webapp
 foreach ($s in $sites) {
 write-host $s.url
 $w = $s.RootWeb;
 $u = get-SPUser -Web $w -limit all | Where-Object {$_.userlogin -eq $login}
 if ($u -ne $null) {
 write-host "`t$($w.url)"
 Set-SPUser $u -SyncFromAD
 write-host "`tUpdated"

After running it, you may get a few errors but you’ll notice their display name and other info is updated.
