Rebuilding the Windows Operating System

Updated

You can rebuild the Windows operating system in the event of a disaster.

Before You Begin

  • Windows Operating System must be installed on the same directory as that of the original computer; otherwise, system state restores will not work.

  • Make sure that the computer has the same fully qualified network name as the original. Match the general hardware configuration (i.e., IDE, SCSI) and the local disk drive to the original computer.

  • The destination host name and the client name must be same as that of the source server name.

  • Make sure the disk drives can accommodate the data being restored.

About This Task

If the operating system of your client is corrupted, you need to re-build the operating system.

During the rebuild you will be prompted for the following system information. Since the computer will be down during the operating system rebuild, you may not be able to access necessary information about the system. It is important to record such information before a disaster occurs.

System Information

How to Get It

Windows Operating System

Use Windows installation media required service packs and hotfixes to install the Windows operating system.

Windows File System Agent

Use Windows File System Agent installation media to install the Windows File System Agent.

Drives

Use the Disk Management utility to record the volumes and sizes of the hard drives in the system, which are needed to recreate the disk configuration in case of hard drive failure. Hard drives must be configured before restoring System State or file system data.

Computer name

Use the same computer name and avoid changing other configuration settings.

TCP/IP Settings

On the command prompt give following commands:

  • hostname - Note down the fully qualified network name

  • ipconfig - Note down the IP address, Subnet mask, TCP/IP domain name for the network, IP address of the domain name server (DNS) settings.

Domain information

Note down the domain in which this computer resides.

Domain password

Note down this information if you are restoring a domain controller.

Local admin password

Note down this information to log on to the computer once it is restored.

Procedure

  1. Rebuild the system hardware if necessary.

  2. Configure hardware devices such as disk arrays and ensure connectivity to all drives.

  3. Using the instructions provided with the software, install Windows operating system and include any previously installed service packs and hotfixes.

    Note:

    • Do not install IIS Services. These services will be restored automatically during the restore.

    • Do not include the server in the domain. Keep it in the workgroup.

  4. Format and partition the hard drives to match their previous configurations.

    Note: When recreating partitions, you can browse the backup data to determine the previous size of the partitions. When you browse the backup set, each drive letter will have its size noted in the browse window.

  5.  Install the Windows File System Agent for all applicable updates on the default install partition of the client computer.

  6. Disable backup jobs on the client.

    1. From the CommCell Browser, right-click the <Client> and select Properties.

    2. Click the Activity Control tab.

    3. Clear the Enable Backup check box and then, click OK. This will disable backup jobs for the client and any scheduled backup jobs for the client will not start during the system state restore.
