Issue with Open Files on Windows Server 2003

I have an issue that I want to see if anyone would have a good solution for.

I have a client with a Windows 2003 File Server.  They have a user who comes in earlier then most users and has to access files for various tasks and reports.  Many mornings he gets the error that some files are in use and he can only access in read only mode.  Most times this is a file that was left open by another user before they went home the day before and not in the building so he must wait for them to arrive.  I'm trying to find a way that this user would have master rights where if another user has it open he could take it over in full control.  Kind of like how an admin can go on to the server and close files out which is what we do for him if the user isn't in the office.  I'm not sure if this is possible or not but thought I'd see if anyone out there has had an issue like this.  


Thanks.
