Network Administration: Windows Server Installation Preliminaries
After you’ve made the key planning decisions for your Windows Server 2008 R2 server installation, you should take a few precautionary steps before you actually start the Setup program. The following sections describe the steps that you should take before you perform an upgrade installation. Note that all these steps except the last one apply only to upgrades. If you’re installing a Windows server on a new system, you can skip the first steps.
Do a complete backup of the server before you begin. Although Windows Setup is reliable, sometimes something serious goes wrong, and data is lost.
Note that you don’t have to back up the drive to external media, such as tape. If you can find a network disk share with enough free space, back up to it.
Checking the event logs
Look at the event logs of the existing server computer to check for recurring errors. You may discover that you have a problem with a SCSI device or your current TCP/IP configuration. Better to find out now rather than in the middle of setup.
If you’ve used DriveSpace or any other disk compression software to compress a drive, you have to uncompress the drive before you run Setup. Neither Windows 2003 Server nor Windows Server 2008 supports DriveSpace or other disk compression programs.
Disconnecting UPS devices
If you have installed an uninterruptible power supply (UPS) device on the server and connected it to your computer via a serial cable, you should temporarily disconnect the serial cable before you run Setup. After Setup is complete, you can reconnect the serial cable.
