I think you might be talking about small(er) environments then. A DR typically involves failing over controller infrastructure for firewalls, NIPS, auditing software, updating load balancers, usually lots of DNS entries etc. People have to be able to connect to the SAN management software to up the LUNS at the target DC etc. Lots of steps have to happen before clients need to worry about DHCP.
In a larger environment, the DC command center will be a lot more than 1 PC - my last project had ~50 per DC. In a DR, we will have a couple of hundred people cycling through (I'm not involved in BCP design directly, so I'm not sure of the details). Those stations need to be static. And in a larger org, you'll find lots of other odd corner cases where you need static as well (to get around a dependency on DHCP, or network or whatever) Cheers Ken From: David Lum [mailto:david....@nwea.org] Sent: Thursday, 2 August 2012 1:25 AM To: NT System Admin Issues Subject: RE: there should be... In those cases I manually set the IP once I realize the station isn't getting an IP addresses, and sometimes I remember to flip it back to DHCP right away, sometimes it's weeks later :). If trying to do this remote yeah, it could be a reason to keep a station static. Of course that makes it prime to be the one station you can't get to if a change ever does happen to a network (BTDT!). In my fairly limited experience (I have 17 years' experience, but only about 7 different Windows networks over the years) as long as the DC's / DHCP/VM Host servers are static, in a DR situation that's enough because if systems aren't getting DHCP then you're not ready for the next steps.
