I am trying to install SQL Server 2008 Express on a Windows XP Pro machine. 3/4 through the installation, it fails with an error '' is not a valid login or you do not have permission. I had followed the instruction from here:
http://www.sql-articles.com/index.php?page=articles/SQL2008/ins_2008.html
I specified a valid Windows user (in admin group) and password and clicked on the button to use the same user for all sql server services. I didn't see any entry in that screen with an empty username.
Why am I getting this error and if I have a blank user defined somewhere, why doesn't the installer make sure such a user doesn't exist?
