Why are objects such as Users, Groups, Computers and Organization Units created using Native Tools not displayed in Directory and Resource Administrator?
Directory and Resource Administrator 6.x
Directory and Resource Administrator 7.x
The Directory and Resource Administrator (DRA) server stores and maintains information in memory for performance purposes which is called the Cache. In order for a computer or user account that was created outside of DRA to show up in DRA, an Accounts Cache Refresh needs to be performed for the domain where the object was created. If an object is created in DRA, the object is simultaneously written to the cache and to Active Directory or the NT SAM. In DRA 6.5, the Incremental Account Cache refresh has been introduced which can be run as often as every 30 minutes for a Windows 2000 domain. For an NT domain, the minimum interval is every 3 hours for an Account Cache refresh.
