Verifying Required System Modules; Installing Windows Nt Server - Netscape DIRECTORY SERVER 6.01 Installation Manual

Verifying Required System Modules

Directory Server is not supported on Windows NT 3.5.1 or earlier releases, or
Windows NT for the Alpha architecture. Neither is it supported on Windows NT
Workstation, because this form of the operating system is not suitable for scalable
Internet or Intranet server deployments. Windows NT Workstation is limited in its
allowable setting for connection backlog. Windows NT Server allows a connection
backlog setting of more than 10, which is necessary for TCP/IP servers under
heavy load.

Installing Windows NT Server

During the installation of Windows NT, please observe the following:
• If there is already an operating system present on the computer, choose to
perform a fresh install rather than an upgrade.
• Format the drives with NTFS rather than FAT, as NTFS allows access controls
to be set on files and directories.
• Specify that the computer will be a stand-alone server and will not be a
member of any existing domain or workgroup. This will reduce dependencies
on the network security services.
• Choose an administrator password of at least 9 characters. Use punctuation or
other non-alphabetic characters in the first 7 characters.
• Do not install Internet Information Server.
• Specify only TCP/IP as network protocol, and do not install any other network
services.
• Always use the latest version of DLL files.
If you are installing on a Windows NT system that has newer DLL files than
those supplied with Directory Server, do not overwrite the newer DLL files
with the versions provided with Directory Server. For example, this situation
can occur if you are running the latest Windows NT Service Pack.
• On Windows NT 4.0, the maximum address space that an application can use
is 2 GB. Because Directory Server cannot use more than 2 GB of virtual
memory, the sum of all caches configured for the server must be strictly less
than 2 GBs. If the size of the entry caches and of the database cache exceed this
limit, Directory Server will exit with an error message.
