I'm assuming VC++. I've never done device driver debugging, but there is a Remote Debugger you might look at that is built into the IDE. (Or was that WinDbg?) Random crashes are hard to trace. Alternatively, instead of the default 64K minidump, you should also look at changing the system settings to provide a more complete crash dump. Right-click My Computer -> Properties... -> Advanced -> Startup and Recovery -> Write debugging information -> Complete memory dump. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
