Delay Occurs When Unlocking Workstation (Windows NT/2000)

Sometimes a noticeable delay occurs when the logged on user or an administrator attempts to unlock a workstation. This because when you unlock the workstation Windows will update the domain list if the cached list's age exceeds two minutes (by default). This age limit can be modified.

1.Open your registry and find the key below..

2.Create a new DWORD value, or modify the existing value, named "DcacheMinInterval" and set it to equal the new cache time-out in seconds (decimal).

Restart Windows for the change to take effect.

Registry Settings
System Key : [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows NT\CurrentVersion\Winlogon]
Value Name : DcacheMinInterval
Data Type : REG_DWORD (DWORD Value)
Value Data : 120-86400 (decimal) (expressed in seconds)
