Here is the thing, I had made a stupid mistake yesterday. I run "route /f" on a remote machine with Windows Server 2008, and this command cleared the routing tables, including the default route, which is fatal.
Since no one is working on the remote side now, I could not restart the machine. This stupid mistake makes me could not reach the machine thought remote desktop, I have tried to access the machine on another machine (in the same LAN with the broken remote machine), but it did not work.
Is there any way I can get the default route back, so that I could access the remote machine by remote desktop again? Any advice is appreciated! Thank you very much!
