SYMPTOMS

A remote debugging session hosted on Windows NT with the target located on a computer running Windows 95 using TCP/IP may fail to acknowledge breakpoints. In addition, pressing CTRL+BREAK interrupts the debugging session leaving you with assembler code rather than source code in the source window.

CAUSE

On the host computer, the Debug tab in the Project Settings dialog box has two executable location fields:

  • Executable for debug session {full executable name as it appears to the host PC}.
  • Remote executable path and file name {full executable name as it appears to the remote PC}.

Using a UNC file specification for these fields results in the same entry in both fields. For example:

   \\server\share\myproj\myprog.exe
                

RESOLUTION

To work around this problem, map a drive to the share and use the mapped file name. For example, from the host computer:

   p: = \\server\share

   Executable for debug session: p:\myproj\myprog.exe

   Remote executable path and file name: c:\myproj\myprog.exe
                

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.
