Oh, I actually meant "bitcoin.exe -server" instead of bitcoind, my bad. Don't know if it makes any difference, though.
I wondered about that aswell. One would assume bitcoind.exe to be a deamon therefor usable for the server.
I have a feeling somehow it's being blocked, but I am not sure... What is a bit frustrating, is that bitcoin.exe has no console-log, and bitcoind.exe no output at all..
The console of the guiminer application doesn't help much either.
Can one set the port for the server?
Now I'll be damned... I just re-extracted guiminer, set the port to 8333 -> connection problems, set the port back to 8332 -> It connected!
