What is vnetsup.vbx

What is the file vnetsup.vbx for, what program installs it, and why did its absence cause my system to crash?

I had to reinstall Windows 98 because this file was missing.  It wouldn't even boot up in safe mode.  I don't know what this file is, and I don't even know what a .vbx file is.  I suspect that some program other than Windows 98 installed that file on the hard drive, because now I cannot find it anywhere, and my system runs fine.  If possible, please explain the purpose of a .vbx file.

A VBX file is:

Short for Visual Basic custom control. A software module that, when called by a Visual Basic application, produces a control that adds some desired feature to the application. A VBX is a separate executable file usually written in C that is dynamically linked to the application at run time and can be used by other applications, including some applications not developed in Visual Basic. While VBX technology was developed by Microsoft, most VBXs have been written by third-party developers. Although VBXs are still in use, the technology has been superseded by OCXs and ActiveX controls.

Whatever that file is, it must be pretty special, there is no reference to it anywhere on the internet (according to and and it is not on any of the computers I have here at home.

This file is linked to what I belive is the vnetsup.vxd. It is located in the network section of the registry. It critical to  using the network capabilities of the os.

That's was vnetsup.vxd (instead of vbx).  All these acronyms can get confusing.

I don't use a network, so why should Windows care if it is missing?
