One of our servers was not used for a long time and this has lead to the Windows not booting up due to Activation issue . It asks me to activate windows , but even if I click on "Yes" the computer just goes back to the login screen where u have to hit ctrl+alt+del to login . Its like a loop , can anyone tell me what we can do about this issue ? I dont want to reinstall the server again . PS : In safe mode I can login , but I cant activate . Is there a fix ? like say to remove this checking and make it work .
