You are an administrator of the Contoso Corporation, which consists of the corporate office, three large sites, and 24 medium sites. You need to make a template library available to all sites. Because the document library is large and contains large templates, the documents must be located at each site. When a template is modified, that document must be copied to all other sites. When a user accesses the document, the user should retrieve the document from the local server, regardless of the site at which is located or visiting. When the site server is not available, users must be routed to another server. Describe the steps necessary to accomplish these tasks.
