34Chapter 3 Then, for each of the machines named in the site preparation file, you run the installation fromthe central installation directory. During these installations, most of the dialog boxes arecompleted automatically using the information in the site preparation file. Finally, you use the client installation on the DVD-ROM to install the Scriptwriter Serviceonto machines that are not named in the site preparation file.The installation procedure supports the following configurations: All servers and scriptwriter machines in one domainThe installation procedure uses Domain\Running User, Domain\Anonymous User, andDomain\IBM® SPSS® Data Collection Group to set up the Interviewer Server services andthe database access group.Note: The domain group cannot be a Local domain group. Domain groups must be created asGlobal, otherwise the DPM Server will not start after installation. All servers and scriptwriter machines in one workgroupThe Running and Anonymous Access users and the Data Collection group that you chooseduring the installation must exist on all servers (including the database server) and scriptwritermachines in the workgroup. The installation procedure uses LocalMachineName\RunningUser, LocalMachineName\Anonymous User, and LocalMachineName\Data Collection Groupto set up the Interviewer Server services, and DBMachineName\Data Collection Group toset up the database access group. All servers except the database server in one domain and the database server in another domainDomains must trust one another (that is, be bidirectional), so the users and group that youchoose during the installation will be visible in both domains. The installation procedure usesDomain\Running User, Domain\Anonymous User, and Domain\Data Collection Group to setup the Interviewer Server services.Note: The domain group cannot be a Local domain group. Domain groups must be created asGlobal, otherwise the DPM Server will not start after installation. All servers in one domain and all scriptwriter machines in another domain, or domain controllerinstallations with two domainsThe domains must have a two-way trust or the server domain must trust the scriptwriterdomain. The group that you choose during the installation procedure must exist on theserver’s domain, and must be created as a domain local group, not as the default globalsecurity group. The users from both domains must be added as members of this domainlocal group. Domain local groups are supported in a native-mode domain only, not in amixed-mode domain. The installation procedure treats this type of installation like one orother of the previous domain-based installations. All servers in a workgroup and scriptwriter machines in a domainThe Running and Anonymous Users and Data Collection Group must exist on all servers inthe workgroup, and the scriptwriter domain user must be synchronized as a local user onthe workgroup servers. The scriptwriter user must be added to the Data Collection Groupon the servers. The installation procedure uses LocalMachineName\Running User andLocalMachineName\Data Collection Group to set up the Interviewer Server services, andDBMachineName\Data Collection Group to set up the database access group.
