请教一个service broker的问题，谢谢
我是用sa登陆的，并且已经建立了CERTIFICATE   EndPointCertificateA
可是为什么下面的语句却报错了呢？

CREATE   ENDPOINT   ServiceBrokerEndPoint
STATE   =   STARTED
AS   TCP   (LISTENER_PORT   =   4022)
FOR   SERVICE_BROKER
        (AUTHENTICATION   =   CERTIFICATE   EndPointCertificateA,
          ENCRYPTION   =   SUPPORTED
        )


Msg   1088,   Level   15,   State   1,   Line   1
Cannot   find   the   object   "EndPointCertificateA "   because   it   does   not   exist   or   you   do   not   have   permissions.


------解决方案--------------------
什么东西?没看明白.

看提示是EndPointCertificateA不存在?
------解决方案--------------------
你用证书的认证方式，却没创建或拷贝证书
------解决方案--------------------
直接使用windows认证

CREATE ENDPOINT [BrokerEndpoint]
STATE=STARTED
AS TCP (LISTENER_PORT = 4022, LISTENER_IP = ALL)
FOR SERVICE_BROKER (MESSAGE_FORWARDING = DISABLED
, MESSAGE_FORWARD_SIZE = 10
, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = DISABLED)
