我在windows xp系统上安装了websphere5.0网络版，启动dmgr，启动node，启动server1后在管理控制台“安全性->用户注册表->本地 OS”中增加控制台用户，认证机制为LTPA，在LTPA 菜单中生成密钥，并在“系统管理->控制台用户”中为控制台用户分配管理员权限。重启服务器，在安全验证模式下用新用户登录管理控制台，到此为止，一切正常。但我按如上次序新增加另一个本地OS控制台用户，并分配新用户为监控者角色后，不能正常停止webshpere，报错如下：
D:\Program Files\WebSphere\AppServer\bin>stopServer server1

检查AppServer下的stopServer.log文件：

同样在DeploymentManager下stopManager也报异常。Access denied for the stop operation on Server MBean due to insufficient or empty credentials

请问应该如何处理？谢谢

报错是因为权限不足或空证书，我又用stopServer server1 -username user1 -password passwd1;stopNode -username user1 -password passwd1;stopManager -username user1 -password passwd1
就可以正常停止了。
