Does anyone know why this is happening?

On a users machine, if I try and run my exe from the network (our file server which is in the same domain as the user machine) I get the message: File "whatever.exe" does not exist.

If I copy the .exe and the two .dll files to the users hard drive and then try to run it, it works fine.

Why can't I run the program from the network?

Thank you for any input.
