[Fix] - SQL Server Error 4064 – Cannot open user default database. Login failed. Login failed for user
Scenario :
Many users have received following error while connecting to the database. This error happens when database is dropped with which few database users are mapped. When that user tries to login the following error shows up.
FIX 1 :
1. Click on Options button in SQL Server’s “Connect to Server” dialog box.
2. Select “Connect to database” as “master” database.
3. Now go back to login tab and connect with any registered user via SQL Server authentication.
FIX 2 :
1. Click Start, click Run, type cmd, and then press ENTER.
2. Use one of the following methods, depending on the kind of authentication that the SQL Server login uses:
For Windows authentication : sqlcmd –E -S [InstanceName] –d master
For SQL authentication : sqlcmd -S [InstanceName] -d master -U [Login_Username] -P [Login_Password]
3. After executing one of the above commands, use the below command:
ALTER LOGIN [Login_Username] WITH DEFAULT_DATABASE = [DB_Name]
4. Finally type GO and press ENTER to save the changes made to the user.
Fix 3 :
To avoid this error, while creating logins, check for the default database option. So now login as administrator or with high credentials, click the appropriate user login and set the default database as master and click ok button.
Fixes are applicable to the following versions of SQL Server:
- SQL Server 7.0 OLAP Tools
- SQL Server 2000 64-bit Edition
