Cannot delete LUSETUP because it is in use by another person or program
So here is the current problem I am having. I have an old version of Symantec Antivirus version 10.x setup files sitting in a folder on my domain controller running Windows Server 03 R2. We havent used this version for years and are currently running Endpoint protection 12.1 with the manager on a completely different server. I was cleaning up the uneeded files on the domain controller but just cannot delete LUSETUP.EXE because Windows is telling me it is in use. Under computer management, I can see that the file is not open, it is not running as a service on the server, and any freeware file unlock application I use tells me the file is ok to delete, but WINDOWS just won't let me. I don't want to have to reboot the server just to delete this file, but I also don't want a useless folder sitting on my server with a single useless file in it. We have close to 1000 computers on our network and is it possible that one of those machines has the process locked? Does anyone know a way to force delete this file? Any help would be greatly appriciated.
