You are logged in to Windows as Domain-User and in process4.biz you
have created this windows user. However, if you try to login to
process4.biz as Windows (Domain) user (when logging in you check “Use
Windows NT integrated Security” flag), this error message appears:
“Failed to authorize user. Either user name or password is not valid for the database”.
The most likely reason is that your Domain-User name begins with a small letter and the Windows-User name that you have added to process4.biz begins with capital letter. Or vice versa.
- You can change the name of the Windows Domain-User
- Change the name of the Windows user in process4.biz via SQL Server.
