解决方法

SQL server has local password policies. If policy is enabled which
locks down the account after X number of failed attempts then the
account is automatically locked down.This error with ‘sa’ account is
very common. sa is default administartor login available with SQL
server. So there are chances that an ousider has tried to bruteforce
your system. (This can cause even if a legitimate tries to access the
account with wrong password.Sometimes a user would have changed the
password without informing others.)

如果您知道另一个管理员帐户,您可以使用此查询解锁它,

ALTER LOGIN sa WITH PASSWORD='password' UNLOCK
