NT4/2K - Prevent workstations from caching of logon credentials

By default, NT workstations will cache the last ten sets of logon credentials received from a domain controller. This reduces the number of times a workstation has to contact a domain controller for verification of a logon request, and it often makes it possible to log on to a domain even when the domain controller isn't available on the network. If you want to prevent these credentials from being cached, as you might if you're running a high-security network, add or modify the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\
CurrentVersion\winlogon

REG_SZ
CachedLogonsCount
Value=0


note: as with any addition/modification to the registry - back it up beforehand !

In Win2k you can set this by going to Control Panel-->Administrative Tools--> Local Security Policy--> Local Policies --> Security Options and set the number of cached logons to 0

(this probably just sets the registry entry you mentioned)

    Thanks, lol! I haven't quite come up with a good new one yet. I was gonna default to one of my older usernames: Cha Zui = tea drunk in Chinese but then decided it too didn't quite fit right. I'm not asian lol... But I am tall, and old spirited which is sort of where the Old Mountain Shadow came about.
  • O Old Mountain Shadow:
    Either way I appreciate the willingness to help me change it! Should I discover something better I'll swap it, but for now ill stay with what I got.
  • The Helper The Helper:
    If you want a change like they said earlier just let us know
