Hi every one
I want to install dotnetnuke on my iis 6.
but when I give the server name and database name to the installer this error is given to me:

Code:
Connection Error(s):
Index #: 0
Source: .Net SqlClient Data Provider
Class: 14
Number: 18456
Message: Sql login failed
I don't know how to fix this error
waiting for your solutions...

P.S
I have Make my own database on my MS SQL server 2008 and I don't want to use the default dotnetnuke database placed on App_data folder.
I fill the database information correctly but it can not access my database
