Description
Defines how long the primary domain controller (PDC) waits for a response from a backup domain controller (BDC) before it considers the BDC to be unresponsive. An unresponsive BDC is not counted against the limit specified in the PulseConcurrency entry, allowing the PDC to send a pulse to another BDC in the domain.
If this value is too high, then a domain with a large number of unresponsive BDCs takes a long time to complete a partial replication. But if this number is too low, then a slow BDC might mistakenly be treated as unresponsive. When the BDC finally does respond, it will partially replicate from the PDC, increasing the load on the PDC.
This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
Note
- In Windows Server 2003, the Net Logon service manages replication only if the replication involves servers running Windows NT 4.0 or earlier. Net Logon for Windows Server 2003 does not manage replication between two servers running Windows Server 2003.
