Description

Specifies how long a backup domain controller (BDC) waits after receiving a pulse before it responds to the primary domain controller (PDC).

The value of this entry must be smaller than the value of the PulseTimeout1 entry, otherwise the PDC will consider the BDC to be unresponsive.

When calculating an optimal value for this entry, remember that the time required to replicate a change to the Security Accounts Manager (SAM) or Local Security Authority (LSA) databases to all the BDCs in a domain will be greater than:

[(Randomize/2) * NumberOfBDCsInDomain] / PulseConcurrency

If this entry does not appear in the registry, then Net Logon determines optimal values for the server based on the domain controller's workload.

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.
