Directory-Enabled Applications Developers can use a number of standard interfaces to write applications that utilize information stored in the Active DirectoryTM service about users, other application and devices. This enables rich, dynamic applications that are simpler to develop and easier to manage. All Active Directory functions are available through LDAP, ADSI and MAPI for extending and integrating with other applications, directories, and devices. 5.0 allows you to host more Web sites per server with high performance. IIS CPU Throttling Limit the amount of CPU time a Web application or site can use to ensure that processor time and therefore better performance is available to other Web sites or to non-Web applications.
Server delivers high performance processing on high performance networks.
Increased throughput increases performance without having to increase network bandwidth. Write Protection Helps prevent errant code from interfering with system operations. Windows File Protection Prevents new software installations from replacing essential system files. Driver Certification Identifies device drivers that have passed the Windows Hardware Quality Labs test and warns users if they are about to install an uncertified driver.
