Many administrators today are testing Microsoft Server 2008, or even testing running Server 2008 as a guest hosted on various virtualization products. There are also plenty of projects not even related to virtualization involving testing applications and services on Microsoft’s newest server operating system. For those looking for a little more time, there is the option to extend the standard Server 2008 evaluation period. The Dugie’s Pensieve blog post Extend the Windows Server 2008 evaluation period (KB 948 472) first made me aware this was possible.

Normally, installing Server 2008 without a key gives you a 60 day evaluation period. As Dugie’s post point out, Microsoft has provided a KB article titled How to extend the Windows Server 2008 evaluation period which fully explains the use of the script and how many times you can “re arm” the evaluation.

From the KB article:

“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.”

The KB article also provides step by step instructions for running the script.

When the initial 60-day evaluation period nears its end, you can run the Slmgr.vbs script to reset the evaluation period. To do this, follow these steps:

1. Click Start, and then click Command Prompt.
2. Type slmgr.vbs -dli, and then press ENTER to check the current status of your evaluation period.
3. To reset the evaluation period, type slmgr.vbs –rearm, and then press ENTER.
4. Restart the computer.
   This resets the evaluation period to 60 days.

Unfortunately, the KB article APPLIES TO section only lists the following versions.
