This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:
2015-04-27 10:10:32.98 Backup BACKUP DATABASE successfully processed 0 pages in 0.451 seconds (0.000 MB/sec).

2015-04-28 17:09:59.87 Server SQL Server is terminating because of a system shutdown. This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several
times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).
Thanks for any help.
