A couple of things to check.有几件事要检查。

Did you add yourself as an administrator on the server (SQL, not the computer)?您是否将自己添加为服务器（SQL，而不是计算机）的管理员？ Unlikely, at least with the logged on account, as you are failing login.不太可能，至少使用已登录的帐户，因为您登录失败。 To fix this, you have to add your account.要解决此问题，您必须添加您的帐户。 To do this without logging in, you need to do something like this - This is 2008, but the concept is still sound.要在不登录的情况下执行此操作，您需要执行以下操作 - 这是 2008 年，但这个概念仍然合理。 Google for other options?谷歌还有其他选择吗？
Do you have mixed mode enabled?是否启用了混合模式？ If so, you can log in with the sa account and password.如果是这样，您可以使用 sa 帐户和密码登录。 And, once in, you can add your account to the admin group like this而且，一旦进入，您可以像这样将您的帐户添加到管理员组
