Ghost and NT 4 backup domain controller

Hello:

I have an NT 4 backup domain controller that hosts Exchange 5.5, and IIS 4.0.

Due to the importance of the server I am thinking of ghosting the hard disk in order to avoid the situation that server’s disk fails.

Assumming that the server’s hard disk fails, if I deploy the ghost image then will it work?. Could you tell me if there will be any problems and how to overcome them in the NT environment.

Normally the server will synchronize with the Primary domain controller but is it so simple?

Thank you in advance.
