OK, I've looked into this some more and it's undeniable odd.
The problem seems to be that the Remote Desktop Connection server doesn't
like being woken from standby by Wake-On-LAN. I don't think the problem is
in anyway related to OpenVPN.
Here's what fails:
1) Put PC into standby
2) Go to another PC (either on the LAN or from home) and wake my Office PC
3) At this point, everything works - I can connect to my shared folders,
ping my office PC etc
4) But RDC fails! It crashed on the log-in
Here's what works:
Exactly the same as above but this time I wake the PC by pressing a button
on the keyboard.
Thanks,
Jack
