AD操作时异常：该服务器不愿意处理该请求。 (异常来自 HRESULT:0x80072035)

需要用到AD操作，在网上找了个ADHelper，随便用下，创建帐号的时候代码如下，运行到  ADHelper.EnableUser(commonName)的时候，：

 DirectoryEntry entry  =  GetDirectoryObject();

              DirectoryEntry subEntry  =  entry.Children.Find(ldapDN);

              DirectoryEntry deUser  =  subEntry.Children.Add( " CN= "   +  commonName,  " user " );

              deUser.Properties[ " sAMAccountName " ].Value  =  sAMAccountName;

              deUser.CommitChanges();

              ADHelper.EnableUser(commonName);

              ADHelper.SetPassword(commonName, password);

              deUser.Close();

               return  deUser;

居然报异常： 该服务器不愿意处理该请求。 (异常来自 HRESULT:0x80072035)，呵呵，还挺人性化的，居然不愿意

找了半天，弄不清楚原因，最后把  ADHelper.SetPassword(commonName, password);放在  ADHelper.EnableUser(commonName);前面，程序就可以通过了，哈哈，无语
