I have a vbscript that converts an nt security event log to an html document (stripping out the events that are not helpful in determining user logons and logoffs). The event log must first be saved as .csv file. Problem: In some circumstances the security event log is captured from a machine that is not live on a network and the GUIDs for the users are not resolved. Is there a way to resolve a GUID to a friendly userid (domain\userid)?
