Yesterday I had to change my windows logon password.
Today, when I try to connect to my local instance of Sql Server 2008 R2 through Management Studio, it gives me an error message. After reading this ( https://stackoverflow.com/questions/5955470/cannot-connect-anymore-to-local-sql-server-2008-database ), I tried to start up the SQL Server process, but it gives me a logon failure:
What should I do next?
check what user account SQL Server is running as. If you set it to e.g. LocalSystem it should work.
In Sql Server Configuration Manager check the account that the Sql services are running as. If you are running it as your account. Update the password or create a new low privileged account for running SQL (best practice). The Localsystem account will work but is not good practice.
