When running Office Communications Server Setup to create an Enterprise pool, the Create Enterprise Pool Wizard requires a SQL Server instance as shown in Figure 1. This is a database instance that the Enterprise pool uses as its back-end server. After the SQL Server instance field, the wizard provides an example that can be confusing. The reason is that unless you plan to reuse an existing instance, most installations are new installations. The language in the wizard might make you think that you need to specify a database instance name that is to be created or that you have to create the instance yourself.
