How could reset zenadmin password

[wyld]

Hi experts
I restore a ZCM Server from all bacup file, when I resore (1)internal CA(2)Server configuration (3) Embedded Syabse , I find out the ZCM could not connect DB. I know maybe the reinstall server zenadmin's password is mismatch with old zenadmin.
Bug my old server is crash, I could not run zman dgc to get old zenadmin's password(it show "Error: An internal error occured. Please check the zman log for more information."). How could I reset zenadmin's password ?
