Ensuring System Clock Accuracy
To facilitate the correlation of date and time stamps in log files with those of
other computer systems, keep your system clock reasonably in sync. As the
NET TIME command requires NetBIOS, which will be disabled during
post-installation system configuration, either a TCP/IP based NTP client should
be installed (such as the shareware program Tardis), or a time radio receiver
attached. See
http://www.ntp.org for more information on NTP clients for
Windows.
Installing Windows Service Packs and Hotfixes
Windows 2000 Service Packs include key fixes that are needed to maintain the
security and reliability of the operating system. The hotfix series contains
important changes for problems discovered after the service pack had been
released.
Directory Server is certified with Service Pack 3 and security patches released by
the OS vendor at the time of this certification. It is recommended that you install
the latest service pack and all hotfixes and patches recommended by the OS
vendor.
Configuring the System Post Installation
The Windows 2000 environment requires tuning to provide optimum
performance for Directory Server in an operational environment. Consult the
Windows 2000 system administrator’s documentation or support channel for
information on Windows 2000 tuning for multi-threaded internet services.
It is recommended that you set the
LargeSystemCache registry key to 0 to limit
the growth of system cache. The
LargeSystemCache has a default value of 1,
which is not suitable for applications such as Directory Server, which do
caching internally.
Also, if there’ll be a lot of connections from clients:
• Change
tcp_time_wait_interval from its default value, which is 240
seconds, to 60 seconds. To do this, at Registry
HKEY_LOCAL_MACHINE\System\CurrectControlSet\services\Tcpip\Pa
rameters
, create a key TcpTimeWaitDelay with value 60.
