Laptop as DC for disaster recovery?

[chicagotech]

We have a single-domain LAN with 2xW2k3 servers, 35 XP workstations and 5 XP

> The PDC emulator also hosts SQLserver and an Access database which is

> Total disaster risks we face are fire and tidal inundation.

> In such event we would need to set up skeleton operation with small LAN to

> (a) Diversion of manufacture and test (electronic PCB assemblies) to other
> company sites
> (b) Sales and customer support.
> (c) Insurance claim for lost components and products.

As long as you back up the system state on a DC you can recreate a new
DC quickly with that backup. I don't see why a laptop would make that
better, particularly as it would not be a suitable DC later.
