Larger sites may have a database machine running SQL Server, and a Web and interview machine
running IIS, the Web Service, Interview Service, and Accessories Service.
Very large sites will probably have separate machines for each service except the Accessories
Service. This will be installed on the machine running the Interview Service.
Generally, scriptwriters access the activities they require by connecting to Interviewer Server
Administration via their browsers. If your site has scriptwriters who work off-line and do not
always have access to Interviewer Server Administration, you can install the Scriptwriter
Service on those machines, and the scriptwriters will be able to create, compile, and activate
questionnaires using desktop activities.
Interviewer Server is
fl
exible with regard to how the various machines are set up. It allows all
machines to be in the same domain or workgroup, or you can have the database server in one
domain with the machines running the other services in another domain.
Note:
If you use more than one domain, the domains must trust one another. It is important that
you consider carefully how your site will be con
fi
gured before starting to install Interviewer
Server, so that you install the correct services on each machine.
Installations using disk imaging or terminal services
With the exception of the Operating System and Microsoft subcomponents, disk imaging
installation techniques (such as those accomplished with Symantec’s Ghost or PowerQuest’s Drive
Image) cannot be used for IBM® SPSS® Data Collection Interviewer Server servers. Interviewer
Server has distinct con
fi
guration information on a per server basis, so imaging a server after
installing Interviewer Server is not a viable option for multiple-server installations.
Interviewer Server cannot be installed using terminal services such as Citrix remote administration
because, unless XP terminal services are used, the user that is logged on does not have rights to
launch services as the interactive user. Interviewer Server can, however, be installed remotely
using a program such as Remote Desktop.
Installations onto a domain controller
Installing IBM® SPSS® Data Collection Interviewer Server onto a domain controller is not
recommended. There are known issues with .NET running on domain controllers and there may
be an additional security risk if IIS runs on a domain controller that is accessible from the internet.
If there is no choice but to install onto a domain controller, you must take the following steps.
E
If you are installing onto a domain controller, and the scriptwriters who will be using the client
installation are located in another domain, refer to
Installation procedures
for further information.
Installing from a downloaded file
You must run the installer as administrator:

Using Windows Explorer, browse to folder where you downloaded the
