I was using Sql Server Management Studio 2008 R2. While being logged in, I accidentally deleted the user "Station-2\Henry". After logging out, I could not log in again with Windows Authentication mode. The error message was "Login failed for user 'Station-2\Henry'. Microsoft SQL Server, Error: 18456""Station-2" is my computer name and "Henry" is my computer administrator name. I guess because I deleted the administrator name in Sql Server engine, it does not grant me the access to the server any more. The problem is I don't have any username and password to log in using SQL Server Authentication. What should I do now?![]() |
