As the business and network infrastructure changes, it's not uncommon for the messaging infrastructure to change as well. Keep track of these changes as they progress through baselines (how the Exchange Server 2003 environment was built) and other forms of documentation, such as the configuration settings and connectivity diagrams of the environment.
The server build procedure is a detailed set of instructions for building the Exchange Server 2003 system. This document can be used for troubleshooting and adding new servers, and is a critical resource in the event of a disaster.
The following is an example of a table of contents from a server build procedure document:
Windows Server 2003 Build Procedures System Configuration Parameters Configure the Server Hardware Install Vendor Drivers Configure RAID Install and Configure Windows Server 2003 Using Images Scripted Installations Applying Windows Server 2003 Security Using a Security Template Using GPOs Configuring Antivirus Installing Service Packs and Critical Updates Backup Client Configuration Exchange Server 2003 Build Procedures System Configuration Parameters Configuring Exchange as a Mailbox Server Creating Storage Groups Creating Databases Configuring Exchange as a Public Folder Server Creating a Public Folder Database Configuring Front-end Functionality Configuring SSL
The configuration document, often referred to as an as-built, details a snapshot configuration of the Exchange Server 2003 system as it is built. This document contains essential information required to rebuild a server.
The following is an Exchange Server 2003 server as-built document template:
Introduction The purpose of this Exchange Server 2003 as-built document is to assist an experienced network administrator or engineer in restoring the server in the event of a hardware failure. This document contains screen shots and configuration settings for the server at the time it was built. If settings are not implicitly defined in this document, they are assumed to be set to defaults. It is not intended to be a comprehensive disaster recovery with step-by-step procedures for rebuilding the server. In order for this document to remain useful as a recovery aid, it must be updated as configuration settings change.

Network configuration diagrams, such as the one shown in Figure 20.2, and related documentation generally include local area network (LAN) connectivity, wide area network (WAN) infrastructure connectivity, IP subnet information, critical servers, network devices, and more. Having accurate diagrams of the new environment can be invaluable when troubleshooting connectivity issues. For topology diagrams that can be used for troubleshooting connectivity issues, consider documenting the following:
Internet service provider contact names, including technical support contact information
Connection type (such as frame relay, ISDN, OC-12)
Link speed
Committed Information Rate (CIR)
Endpoint configurations, including routers used
Message flow and routing
