Ensuring That the Appropriate Infrastructure Exists

The highly scalable LTI deployment infrastructure uses a hub-and-spoke topology for replication of content; therefore, first nominate a deployment server in the production environment that will perform the role of the master deployment server. Table 8 lists the required components for the master deployment server.

Table 8. Master Deployment Server

Required component	Purpose/comment
Windows Server 2003 R2	Required to support DFS-R
MDT	Contains the master copy of the deployment share
SQL Server 2005	Must be a full version to allow replication of the MDT DB
DFS-R components	Required components for replication of the deployment share
Windows Deployment Services	Required to allow network PXE-based installations to be initiated

When you have selected the master deployment server, provision additional servers at each site to support LTI deployments. Table 9 lists the required components for the child deployment server.

Table 9. Child Deployment Servers

Required component	Purpose/comment
Windows Server 2003 R2	Required to support DFS-R
Microsoft SQL Server 2005 Express Edition	Receives replicated copies of the MDT DB
DFS-R components	Required components for replication of deployment share
Windows Deployment Services	Required to allow network PXE-based installations to be initiated

Note Windows Deployment Services must be set up and configured on each child server, but it is not necessary to add boot or installation images.
