Procedure

1. Ensure that OfficeScan clients can upgrade the client program.
   1. On the OfficeScan 10.6 SP3 web console, navigate to Networked Computers → Client Management.
   2. Select the OfficeScan clients to be rolled back.
   3. Click the Settings → Privileges and Other Settings → Other Settings tab.
   4. Enable the Clients can update components but not upgrade the client program or deploy hot fixes option.
2. On the OfficeScan 10.6 SP3 web console, navigate to Updates → Networked Computers → Update Source.
3. Select Customized Update Source.
4. On the Customized Update Source List, click Add.
   A new screen opens.
5. Type the IP addresses of the OfficeScan clients to be rolled back.
6. Type the update source URL.
   For example, type:

   http://<IP address of the OfficeScan server>:<port>/OfficeScan/download/Rollback
7. Click Save.
8. Click Notify All Clients.
   When the OfficeScan client to be rolled back updates from the update source, the OfficeScan client is uninstalled and the previous OfficeScan client version is installed.

   Tip Administrators can speed up the rollback process by initiating a Manual Update on clients. For details, see Updating OfficeScan Clients Manually.

9. After the previous OfficeScan client version is installed, inform the user to restart the computer.
   After the rollback process is complete, the OfficeScan client continues to report to the same OfficeScan server.

   Note After rolling back the OfficeScan client, all components, including the Virus Pattern, also roll back to the previous version. If administrators do not roll back the OfficeScan server, the rolled-back OfficeScan client cannot update components. Administrators must change the update source of the rolled-back OfficeScan client to the standard update source to receive further component updates.
