Appendix 2: Alternate recovery method
If you do not want to use a unique name when rebuilding the original source, use the following
instructions.
1. On the target, open the Failover Control Center (Start, Programs, Storage Mirroring, Failover Control
Center).
2. Select the target machine that is currently standing in for the failed source.
3. Highlight the failed source and click Failback. The failback script created earlier will automatically run.
During failback, Windows Event Viewer and the Storage Mirroring log record the failback events.
When failback is complete, the target will have the Exchange services stopped and the users
repointed back to the source that you will be rebuilding.
4. Reconnect the source to the network.
5. On the target, when prompted to stop or continue monitoring of the source, select Stop.
6. Install Windows on the source, if necessary, configuring it as a Windows 200x member server with the
same name and IP address as the original source.
7. Apply any Windows 200x service packs or patches.
8. Install Storage Mirroring, if necessary.
9. Connect the source to the network and join the domain.
a. On the source, right-click My Computer and select Properties.
b. Select the Network Identification tab and click Properties.
c. Under Member of, change to Domain and specify the domain name.
d. Click OK.
e. When you are prompted for a domain account, specify an account with permissions to add a
workstation to the domain.

10.After the source reboots, log in as the domain administrator or an equivalent account. Verify that the
account has full Exchange Administrator rights.
11.Using the Exchange CD, start the Exchange installation on the source using the following command:
<cd drive>:\setup\i386\setup.exe /DisasterRecovery.
12.At the Component Selection dialog box, set the Action column to Disaster Recovery for all of the
components that were originally installed on the source (before it failed).
13.Verify that each of the components selected are installed in the same location on the source as they are
on the target. If not, modify the location of each component to match the target and original source
configuration.
14.After selecting the proper components and location, click Next to continue the install.
