NT4 will update the domain list if the cached list's age exceeds two minutes. This can cause delays when unlocking a workstation.

Windows NT4 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 Adjusting the following registry entry allows modification to the time period in which the domain list becomes out-of-date.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.
Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Name: DcacheMinInterval
Type: REG_DWORD
Value: 120-86400(decimal expressed in seconds)
