Dear All, We were having a Server As Domain Controller called DC1.Mydomain.com this server had several OU and each OU inside it, and it has a group Policy applied to it. we used to take the Backup of This server as :- 1- System State . 2- SYSVOL Folder. for some resoans, this server has been formatted and completely formatted. Now, i did not take a backup from the Group Policy which i assigned to the Users OU at all. I want to implement the same group policy on the same OU as Before . So, i am thinking of another IDEA, Please Follow it with me. 1- As long as i have the Backup from the Domain Controller which is SYSTEM STATE & SYSVOL , i will install Windows Server 2003 on onther server & i will create the Domain Controller with the same name but without any Configurations at all on ( New Server ) . 2-Once the Windows Server 2003 installed and configured completely , i will restart it , and i will choose F8 to choose ( Active Directory Disaster Receovery Mode ) . 3- i will restore the Backup as we know. But , while i am doing it, i Discover that, i forget the Password of the Domain Controller in Disaster recovery mode , & i found that , i am Unable to Login , at F8 Choice . Please, can any one Help me & guide me , to see what is going on & how to solve this situation in Order to solve it . as soon as possible . Please Urgent Help.
