Replications Issues

Question : How to troubleshoot replication issues between ADC & RDC

Diagnosing Tools :use Dcdiag, netdiag, eventlogs,replmon,repadmin
Possible reasons :
DNS issues, verify DNS from problematic ADC, verify SRV records, verify name resolution from ADC & RDC
Network Link issues: verify network connection is proper ,
AD site & services configuration problems: verify AD site configuration parameters with other sites
Services:Verify FRS Services & other dependancy services are running properly
Network Ports : 135 should be open , RPC dynamically uses ports above 1024, so none of those ports blocked in both direction ( RDC to ADC / ADC to RDC )
