Extend Windows Server 2008 evaluation period

By default Windows Server 2008 runs 60 days without being activated. But after this period, the server will prompt the annoying message during login "Evaluation period expired". Microsoft itself provides a tweak for this by extending the evalutaion period. The evaluation period can be extended for another 60 days upto three times. So in effect we can run the server for 180 + 60 days.

This could be done by executing the below commands:

To view the license status

slmgr.vbs -dli 

To extend for 60 days

slmgr.vbs -rearm
