The Lock XP provides complete user access control and system security for any computer running Windows 95 to Windows XP (with Fast User Switching [also supports Terminal Server connections].) Windows Server 2003 is also supported. All user security is group based configurable by any members of the Administrators group. User security data is stored locally or on a shared network folder. The Lock XP, the local Windows system, a Netware Server, a Windows NT server, or a remote Lock XP Security Manager server, may verify user passwords.
