After cloning 2003 server, because of hardware change you can see information that you have to activate Windows.
Your system probably has no drivers installed, so you will not be able to connect to the network and activate it again.
The solution is to do workaround for the time of installing drivers.
This omits activation and let you install whatever you need before turning it back off.
1.Open your regedit RUN > REGEDIT
2.Find key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WPAEvents
3.see the string OOBETimer
4.Double click.change all content with this one FF D5 71 D6 8B 6A 8D 6F D5 33 93 FD
5.Right Click on WPAEvents(Regedit)and choose Permissions
6.Window will show up,click to System and check all of Deny Listbox
7.Restart Your PC
To complete your device settings, it's good to get rid of old hardware that is hidden now and cause problems.
