I am trying to mine Bitcoin on my CPU in Windows Server 2008 R2 Datacenter. I know about the consequences of CPU-only mining. I have downloaded GUIMiner - title bar looks like this:

However, when I configure it (more info below) and hit 'Start mining!', nothing happens - bottom bar looks like this:

My Setup

Miner: Ufasoft CPU miner

If anyone can help get this working, it would be much appreciated!

  • Is the path to your miner correct? Try moving it to a location other than your desktop, like c:\

According to mining.bitcoin.cz, getwork protocol is removed. Use the stratum protocol instead. stratum.bitcoin.cz:3333

Getwork protocol support ended. Please be sure your miners support Stratum protocol. You can still use your old getwork miners with Stratum proxy installed on your mining rig.

  • go to C:\Program Files\Ufasoft\Coin

  • then rename the "coin-miner.exe" to "bitcoin-miner.exe"

  • then in Ext. path on GUIminer enter C:\Program Files\Ufasoft\Coin\bitcoin-miner.exe
