The reason that this is kinda of a problem is because I'm using substring and of course the string is just too short.

string msg = "Name Taken";
byte[] byData = System.Text.Encoding.Default.GetBytes(msg);
socketData.m_currentSocket.Send(byData);
socketData.m_currentSocket.Close();
m_workerSocketList.Remove(socketData.m_currentSocket);
m_clientCount--;

                }
                SocketPacket theSocPkt = new SocketPacket(soc, clientNumber);
