Hi. I set up a new mining rig, using Windows, Claymore. All I did was plug video cards in, and downloaded Claymore miner. Created a batch file, and copied exact settings from previous miner, only changing minername (everything else is exact copy from original miner batch file). I left it mining for 8 hours, and yet, it's not seen. Only 1 rig is seen. Hash rate didn't increase. Did I miss anything?
