Hi everyone,

I am new to programming and dot net nuke.

while trying to instal DNN on windows XP i had  a couple of issues.

Most I could resolve, thanks to the thread here

I still get an error while creating the user name in Microsoft SQL Server Managment Studio Express

when I right-click on Users --> New Users the Database User - New dialogue box is displayed.

I enter the login which is the windows authentication (domain\username)

I select db_owner from both the 'Schemas owned by this user' and 'Database role membership'

when I click okay, it prompts me to enter a username.

when I enter a username i get the following error

The Login already has an account under a different user name (Microsoft SQL Server, Error: 15063)

any leads on how I can resolve this?

Thank you for your time and help with this.

cheers!
