Doesn't work that way. If you're going to solo and use the rpc server you just need one with a wallet and point your other client to that wallet.@PressQ: You have rpcport=28332 in your rieconf.conf file in %appdata%\riecoin? I hope you're planning to solo mine with quite a few machines. I had trouble finding blocks with 176 threads. I'd suggest joining a pool regardless.
