Hi Anyone

I installed my domain services and registered my domain name with dcpromo, after the restart i have to logon with my admin account, and i forgot my password to my admin account, after doing dcpromo it deletes the other users on the server that was created, now i cant log in, any suggestions to sort out this litttle problem?

i tried safe mode, still need the admin password and same goes to repairing the computer, cant even log onto safe mode with command prompt as it keeps on asking me for the admin password.

please help as this is very urgent 

Hi Dave,

Do you know the DSRM mode password, if yes you can log in in DSRM mode

and reset admin password

Also you can try 3rd partly tools (but not sure if its going to work)

Hiren's BootCD 

Final option will be, if its first time log on issue, then you dont have any information on your AD.

You can format your servers and re install the AD via DCPROMO.

Hope this helps.

Regards,

unfortunately i do not know the DSRM mode password, ill try Hiren's and let you know, thanks for your help
