Hi,
I’ve got windbg hooked up to Win2K SP0/SP1 free and was doing
some random network fsd testing and got hit with a really annoying
breakpoint.
If you bring up explorer or My Computer and right click on any
file on a network file system drive, windbg wakes up with the
breakpoint below. “Go”-ing from there seems to work ok. Doesn’t
occur for non-network file systems.
Anyone else seen something like this? There a workaround?
Or is just me?
Pete
