SUMMARY

A noticeable delay occurs when the logged on user or an administrator attempts to unlock a workstation.

MORE INFORMATION

Windows NT 4.0 will update the domain list if the cached list's age exceeds two minutes (by default). This feature is beneficial to users from a newly trusted domain who need to log on to workstations or servers that have been locked by a previous user.

Adjusting the following registry entry allows modification to the time period in which the domain list becomes out-of-date. The valid range for this entry is 2 minutes (default) to 1 day, specified in the number of seconds. Note that modifying this value could result in users not seeing the current domain list.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

To modify this value, perform the following steps:

  1. Start Registry Editor (Regedt32.exe), modify (or create if necessary) the following: 

          Hive:   HKEY_LOCAL_MACHINE
      Key:    Software\Microsoft\Windows NT\CurrentVersion\Winlogon
      Value:  DcacheMinInterval
      Type:   REG_DWORD
      Data:   120-86400 (decimal)(expressed in seconds)

  2. Quit Registry Editor and restart your computer for these changes to take effect.
