Determines how often the list of domains in the Unlock Workstation dialog box is updated. The list of domains is updated before it is displayed to the user if its age exceeds the value of DcacheMinInterval.
The domain list saved in a memory cache on the local computer. When the user unlocks a workstation (or server), if the list is more than two minutes old (the default), the system retrieves domain data and updates the list. The short update interval ensures that the domain list is current. However, refreshing the list can cause a noticeable delay.
You can use this entry to increase the time between domain list updates and eliminate some of the delay. However, if the domain list changes between updates, users might not see the most current list of domains.
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
