Specify a fixed-port for RPC-based replication

WP on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\

  • For RPC replication between sites: Replicator inter site packet size (objects) & Replicator inter site packet size (bytes)

WP on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\NTDS\Parameters to modify the registry entry AvoidPdcOnWan

Modify the thresholds that make the KCC exclude non-responding servers when it recognizes that a DC has failed or is unresponsive

The following registry entries (with registry path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameter) are added/modified (with the REG_DWORD data type):

For replication between sites:

  • IntersiteFailuresAllowed and MaxFailureTimeForIntersiteLink (secs)

  • For optimizing connections within a site: NonCriticalLinkFailuresAllowed and MaxFailureTimeForNonCriticalLink

  • For immediate neighbor connections within a site: CriticalLinkFailuresAllowed and MaxFailureTimeForCriticalLink

Thus, appropriate permissions required to Create and/or modify these registry keys will be required to delegate the operation
