Hello Chandru, Evaluating Windows Server 2008 software does not require product activation. Any edition of Windows Server 2008 may be installed without activation, and it may be evaluated for 60 days. Additionally, the 60-day evaluation period may be reset (re-armed) three times. This action extends the original 60-day evaluation period by up to 180 days for a total possible evaluation time of 240 days. Note: In the Windows Server 2008 Evaluation DVD package, there is a 120-day initial evaluation period. You can extend the evaluation period to 240 days. To extend the initial evaluation and testing period, follow the steps in this Microsoft Knowledge Base article. http://support.microsoft.com/kb/948472 Regards, Ravikumar P

Hi, Below information quoted from a MS blog: The evaluation is available in ISO format. Web, Standard, Enterprise and Datacenter editions are available via the same download. You will be prompted for edition installation at setup. Evaluating any version of Windows Server 2008 R2 software does not require entering a product key, however will require activation within 10 days. Failing to activate the evaluation will cause the licensing service to shut the machine down every hour (The 10 day activation period can be reset five (5) times by using the rearm command. See below for further information on activation rearm). Once activated, the evaluation will run for 180 days. After this time, you will need to uninstall the software or upgrade to a fully-licensed version of Windows Server 2008 R2. For more information please refer to following MS articles: Windows Server 2008 R2 Evaluation (180 days) http://blogs.technet.com/b/aviraj/archive/2009/08/15/windows-server-2008-r2-evaluation-180-days.aspx Download Windows Server 2008 R2 with Service Pack 1 http://technet.microsoft.com/en-us/evalcenter/dd459137.aspx Lawrence TechNet Community Support
