multithreaded server in python

[newbi3]

I am re-writting an application I wrote in java in python. The problem I am having is even though I have multi-threaded the server I can only get 1 client to connect each time the server runs. Here is the error I am getting

socket.error: [Errno 104] Connection reset by peer

Here is the server which gets the connection and passes it off to a new thread

def startServer():
    
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((host, port))
        
    Misc.mmrghPrint("Zombie Server Started")
        
    while 1:
        s.listen(5)
        Thread(target=ZombieThread.authenticate(s.accept()), args=(s.accept())).start() # <-- Here
        pass
        

Here is the thread that it is passed off to.

def authenticate(socket):
    
    conn, addr = socket
    zombieIP = Misc.parseAddr(addr)
    
    # Client to Server Challenge
    ClientSecretNum = 547623564
    key = int(Misc.recvDecrypted(conn, 1024))
    Misc.sendEncrypted(conn, key + ClientSecretNum)          
    
    # Server to Client Challenge
    ServerSecretNum = 6992825753837
    challengeNum = randint(1111111111111111, 9999999999999999)
    Misc.sendEncrypted(conn, challengeNum)
    respondse = int(Misc.recvDecrypted(conn, 1024))
    
    if respondse != (challengeNum + ServerSecretNum):
        Misc.mmrghPrint("Could not authenticate zombie from " + zombieIP)
        conn.close()
    else:
        Misc.mmrghPrint("Zombie connected form " + zombieIP)
    conn.close()

Maybe someone here can shed some light onto what my problem is and save me from bashing my head into a wall!
