Utilities

The following utilities can be used with the Application Manager.

• DNS Failover (DFO) utility—The DNS Failover utility (dfo.exe) can be used in the failover and failback scripts to delete and add host and reverse lookup entries so that the source host name will resolve to the target IP address.
• Target Data Verification (TDV) utility—There are several options available in the Target Data Verification utility for performing a verification of the target data. The functions in this utility allow you to use a command line interface to perform the same target data verification tests that you can using the Application Manager interface.
• Exchange Failover (EFO) utility—There are several options available in the Exchange Failover utility for configuring Exchange for failover and failback.
