I think we have an in-house hacker in our company. I have a Windows 2000 server that I have gone to Local Security Policy > Local Policies > Audit Policy and turned on Success, Failure to "Audit directory service access, Audit object access, audit system events". I went to a particular directory that we've been having problems with missing files and right-clicked, selected Properties, Security tab, Advanced button, added "everyone" to the auditing tab. I just noticed the following in the Security Event Viewer that I haven't seen before. What is this? "A trusted logon process has registered with the Local Security Authority. This logon process will be trusted to submit logon requests. Logon process name: KSecDD."
