Additional available hard-disk space may be required if you are installing over a network. For more information, see the Windows Server product site.
Installation and Activation
If you need more time to evaluate Windows Server 2008, the 60-day evaluation period may be reset (or re-armed) three times, extending the original 60-day evaluation period by up to 180 days for a total possible evaluation time of 240 days. After this time, you will need to uninstall the software or upgrade to a fully-licensed version of Windows Server 2008.
If you wish to extend the initial evaluation and testing period, see How to extend the Windows Server 2008 evaluation period and follow the instructions.
