I usually send the remote PC to hibernation
or simply disable the network connection on the target
(right-click - disable, in systray or control panel\network connections).
I simply unplugged the LAN cable, but then I get an error immediately
Did you try to do that on the target machine?
I also get the error message immediately, if I disable the network connection of the PC where TC is running on,
but TC hangs if the server/target PC is cut off.
This way the local PC still has access to gateway and DNS server etc., only the server with the share is not reachable.
After some more testing: TC only hangs when it has opened at least one subdir on the share:
- \\server\share : no problem, TC shows "connecting" dialog.
- \\server\share\dir : TC hangs until the error message appears.
I hope you can reproduce it this way?
BTW, I have auto-refresh disabled here, so I have to press Ctrl+R for reloading:
