Something is wrong if you are still getting shares. Did you add rpcallowip=*, rpcuser=your_user_name, and rpcpassword=your_password to bitcoin.conf?
If you mining on the computer with the bitcoin server then the ip address and port should be 127.0.0.1 and 8332 respectively. If I remember correctly.
*IP address of your miner, assuming you mine on a separate computer from your server.
Hope this helps,

Hmm, I did that, yea, so it is kinda weird why I'm still getting shares...
