Question about "Disaster Recovery" for ISA

Hello,

I have a question about a "disaster recovery" for ISA Server

This is my network archetecture

LAN --- ISA SRV --- Internet

I install ISA Server Enterprise Edition and on my LAN I have 2 publish
servers an Exchange Server and a Web Server.....
On my ISA server, I have only one Hard Disk..... Suppose that my hard disk
fail(crash), How can I rebuild the server.

If a replace the defect hard disk with a new one, I make a fresh install
of Windows 2000 + SP, I reinstall ISA Server Ent. Ed. Does the
installation of ISA reclaim all the configuration settings from Active
Directory .....? If it's not possible does it mean that I have to recreate
manually all my publishing rules and others settings ......? Does I have
to make a restore of the "System State" after reinstalling Windows 2000
SRV and before reinstalling ISA ....?
Does it exist a switch /disasterrecovery for ISA like it exist for
Exchange2k ....?

In short, can you explain me the procedure to rebuild the server or maybe
does it exist a MS doc that explain that .....?

Thanks very much for your help.
