Here’s a nice new GUI based tool which shows you the status of AD replication in your forest.
A brief overview of this tool from MS below.
The Active Directory Replication Status Tool (ADREPLSTATUS) analyzes the replication status for domain controllers in an Active Directory domain or forest. ADREPLSTATUS displays data in a format that is similar to REPADMIN /SHOWREPL * /CSV imported into Excel but with significant enhancements.
Specific capabilities for this tool include:
- • Expose Active Directory replication errors occurring in a domain or forest. .
- • Prioritize errors that need to be resolved in order to avoid the creation of lingering objects in Active Directory forests.
- • Help administrators and support professionals resolve replication errors by linking to Active Directory replication troubleshooting content on Microsoft TechNet. .
- • Allow replication data to be exported to source or destination domain administrators or support professionals for offline analysis.
