I
Have received following question nearly 10 times in last week though
Emails. Many users have received following error while connecting
The database. This error happens when database is dropped for which is
Default for some of the database user. When user try to login and their
Default database is dropped following error shows up.

Cannot open user default database. Login Failed.
Login Failed for user 'username'. (Microsoft SQL Server, error: 4064)

The fix for this problem is very simple.

Fix/workaround/solution:

First click onOption>
Button of "Connect to server" prompt.

Now change the connect to database to any existing database on your server like Master or MSDB.

Now click on connect and it will successfully log you in. Once you
Login in the system run following statement for your username and it
Shocould fix your problem.Make sure to replace [test] With your username and master with yourdatabase name.

ALTER
LOGIN [test]
WITH
DEFAULT_DATABASE
=
master


Go
