Check comment by “Scott J Baldwin - Posted on Thursday, March 30, 2006 8:28:58 PM”.
Main points from his reply:
- Delete C:\Documents and Settings\USERNAME\Local Settings\Application Data\Microsoft\Microsoft SQL Server Data\SQLEXPRESS.
Remember to replace USERNAME with your username.
- Also check if the SQL service account has the necessary permissions.
- It is possible to attach to databases in the traditional by edit the connection string and delete the "user Instance=true". User Instances just make it easier (when it does work) to work with databases as though they were files.
Thanks Scott J Baldwin.
