Microsoft VHD

I have downloaded the MS ISA virtual hard drive and MS Virtual server 2005 R2, installed both of the software succecfully and were able to run the server by username :”Administrator” and Password :”Evaluation1″.

But as soon as i login, it tells me to activate the windows and halting the system at this point.

If this is an evaluation version, then why it is asking for product activation. i have installed it on windows 2003 std server edition also on a thirty day trial version.

Can somebody help me, and let me know how to overcome this.

Thx.
