DirectSound packed in (DirectSoundCreate() caused my app to hang), and remote desktop doesn't have an option to restart in the start menu. So I thought I could do "shutdown /s" to restart. 29 seconds into the 30 second shutdown period, I realised that "shutdown /s" shuts the server down.
So it looks like I'll be going back to Edinburgh this weekend to start up my server...
I believe it may also be possible in TaskManager, but I haven't used that in ages.
