Deployment Solution

I insatlling DS 6.9 on a Windows 2003 server and i have install SQL 2005 express in mixed mode. Now i get error that the databse can not be found. After reboot the database is found but i cann not logon.
Invalid credentials.

I'm sure i use the correct username and password but still it is not able to install the database.

Help is very much appreciated.

What i usually do is add the used account to the three sql accounts that are created after the installation of SQL 2005 express.
Go to my computer and select manage.
go to users and groups of the local machine.
In groups you will see three new accounts that are created.
Add the local administrators group to the three groups.

Then try it again.
It helps for me.

Thank you.
After adding the username to the groups the sql server is found and the database now works.
