Restoring Active Directory on new hardware

Dear Reader,

We have a domain controller which works as DC and exchange server.I would like to restore it to new hardware and then split DC and exchange on different servers.

The process I followed is as followed ….

1)Take system state beckup of the old domain controller.

2)Installed OS on the new server.

3)From directory services restore mode on the new server I had restored the system state date. Then re-started the server.

4)The server never comes up and keeps on restarting.

Can some body help me in this matter as guide me how to complete the restoration process.

Thanks in advance.
