Cannot Run Real Mode Under Enhanced with SHARE (58243)

The information in this article applies to:

Microsoft Windows 3.0
Microsoft Windows 3.0a

This article was previously published under Q58243

SYMPTOMS

If you run SHARE, run Microsoft Windows 3.0 in 386 enhanced mode, start an MS-DOS prompt, and run real mode Windows 3.0 in the virtual machine, you receive the following error:

Sharing Violation error reading drive C:

CAUSE

This behavior is by design. With SHARE running, the different virtual machines running act just like different network workstations.

MORE INFORMATION

This problem is exactly the same problem as two workstations on a network trying to run the same installed version of Windows from a network server. You must set things up properly for this to work. All of the files that Windows opens (*.INI, *.DLL, *.EXE, *.DRV) must be marked read-only with the MS-DOS ATTRIB command or you will get sharing violations. The ATTRIB syntax for read-only is as follows:

   ATTRIB <filename> +r
