For the Windows 2000 Server exam you are required to be familiar with the essentials of IIS 5.0,which is installed by default on a new Windows2000 Server installation, and upgrades systems with IIS 4.0. The two main features of IIS remain its functionality as both a web and ftp server,which we’ll concentrate on here. Note that many other services do exist under IIS, including the ability to act as an SMTP (mail), NNTP (news), or streaming media server.
After IIS 5.0 is installed, two new user accounts are created by default, and placed in the Users container. One, called IUSR_computername, is provided for the purpose of allowing anonymous access to the IIS-based system. The other is called IWAM_computername, and is the account under which IIS runs. This is used to start scripting applications, for example.
IIS will also create a folder called Inetpub on the IIS system, and subdirectories of this folder provide the working roots for installed services.For example, wwwroot is the location of the default website, while ftproot houses the root directory for ftp connections. While these directories are used by default, others can be created and placed in different folders or partitions if this better meets your needs. It is usually best, however, to keep everything situated in a single location in order to simplify the administrative process.
IIS services are managed using the Internet Services Manager tool. You can access the master property sheet for a server by right-clicking the server and choosing properties. Settings set on the master property sheets for the WWW or FTP services will be inherited by all new sites you create. The master properties allow you to control settings such as the amount of bandwidth dedicated to each server, registered MIME file types, and server extensions, which includes server usage optimization.
