h1. {anchor:acrne} Calendar Server Post-Configuration Tasks
After you install the Calendar Server software and run the Calendar Server configuration program ( {{csconfigurator.sh}}), you must perform some configuration settings and changes that the Communications Suite installer and Calendar Server configuration utility do not make. You must manually make changes to the following two items by editing the {{ics.conf}} file:
* *DWP and CLD Configurations.* Enable the CLD cache option. This cache stores the DWP host server information for calendar users and thus reduces calls to the LDAP directory server.
* *Default Time Zone.* Change the default time zone if you are not in the Americas/New York time zone.
For more information on these changes, see the [_Sun Java System Calendar Server 6.3 Administration Guide_|http://docs.sun.com/doc/819-4654].
