10. You should see an error window that pops up explaining that the MBES was unable to contact BE-CAS. (Figure 6)
Click OK on the Error dialog, and then the Next button after, this will force the MBES into standalone.

Note: If the ERROR popup does NOT happen then Backup Exec detected a server with the same name as the CAS
on the network. If it is the real Central Admin Server(CAS) and it is still running correctly you should be able to remove
the MBES from the storage tab on the CAS and this will remove it from that system and make the MBES standalone
after service restart on the MBES.

11. Click the Install button on the Summary page to complete the process.

12. After the installation has complete, open the Backup Exec Console/UI and add any storage devices that may be needed.

NOTE: In a restore scenario you may also need to run an inventory and catalog of the storage location. This depends on the previous catalog method in place at the time of the original backup job and whether or not the MBE backed up and duplicated to the CAS or the CAS backed up and duplicated to the MBE.

13. Once the Central Admin server is back online, the MBES can be re-joined using the traditional method.
