Disaster recovery

I’m currently undergoing a project for disaster recovery of our NT servers.
I was wondering if anyone can point me to the right direction of where I can find some useful information and also sample documentations on this.
I have done some screen captures of the NT servers (PDC, BDC, Member servers)with their network configuration, hardware configuration etc.. etc..
but was wondering if theres any useful info that I can use for documentation of our NT server disaster recovery.
TIA
