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

Note Image Note

In Windows 2000, the Net Logon service manages replication only if the replication involves servers running Windows NT 4.0 or earlier. Net Logon for Windows 2000 does not manage replication between two servers running Windows 2000.

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
