WhoHasIt is a Windows application that lets the administrator quickly check who is using a file on the server. The easy to use windows interface is far simpler than trying to do the same job using RCONSOLE/MONITOR. The program displays a list of all the users with that file open, and the option to send the user a message, or clear the connection is provided. The program also displays any record locks held on the file and it is ideal for tracking down database problems.
