Cannot open database from web

[David C]

I am getting the message below trying to open the SQL 2005 db in
default.aspx.

System.Data.SqlClient.SqlException: Cannot open database "Mydata" requested
by the login. The login failed.
Login failed for user 'MYXP\generic'

The web site is on an XP machine with 2005 Express. I setup a login called
generic on our domain and then put that login and password into the identity
impersonate section of web.config
Is something more than domain user needed to get into the web application?
The web is strictly windows authority. Thanks.

Mark,
I thought that having "Domain Users" was enough. Am I wrong? Thanks.
