Before running Application Manager multiple times (for example, when re-enabling protection after a
failover/failback), save a copy of your post-restore and pre-failback batch files. After Application
Manager executes, replace the default script file(s) with the customized file(s) that you saved.
Force AD replication
(Default = selected) When selected, replication is initiated from the domain controller with which the
source or target server communicates. This will be done each time the Exchange Failover utility
(exchfailover.exe) is executed from within the failover/failback scripts. For more information about
using the Exchange Failover utility, see Using the Exchange Failover (EFO) Utility on page G-1.
Disable Force AD Replication if you do not want Active Directory changes to be replicated.
In the Max wait time for AD replication field, enter the maximum time you want to wait for Active
Directory replication to complete before continuing on with the failover/back process. The default is
30 minutes.
Target(ed) domain controller
This field allows you to specify the name of the domain controller where updates will be made during
failover and failback. If this field is left blank, the default or Active Directory-determined domain
controller will be used.
By default, the domain controller is resolved through Windows.
NOTE: The wait time is a factor determining when failover is complete.
If replication exceeds the amount of time specified, a log entry is created and replication
continues. If it is exceeded, failover is not reported as incomplete or failed.
NOTE: The Target(ed) domain controller field is only available for Exchange 2003. It is not
available for Exchange 2007.
You must enter the name of the domain controller. IP addresses are not valid for this field.
