>I have a client who is experiencing an error #1104. The description is so vague - "An error was returned by the operating system while Visual FoxPro was attempting to read a file." Can anyone help me to understand exactly what this error could be refering to? This software ran perfectly yesterday. Today the user had some trouble starting this particular computer. When the computer finally started and they began using my software they ended up getting this error message. I just can't figure out exactly what is causing it.

That can be caused by hardware problems, or network software problems, also. It sounds like that machine has problems that should be addressed by an administrator (and it's not the fault of vfp, probably).
