Just a Quick tip for how to force replication on all Domain Controllers and all partitions. And this is by using the Repadmin tool with switch syncall.
If we look at the tool, we will use the Following switches.
/A Synchronizes all naming contexts that are held on the home server.
/P Pushes changes outward from the specified domain controller.
/d Identifies servers by distinguished name in messages.
/e Synchronizes domain controllers across all sites in the enterprise.
/q Runs in quiet mode, which suppresses call back messages.
And since with this command you can specify what server to sync from we use powershell to get all Domain Controllers. NB on server 2008 R2 you need to load the Active Directory poweshell module.
Get-ADDomainController -Filter * | % { repadmin /syncall $_.Name /APdeq }
