System.Data.SqlClient.SqlException: Login failed for user 'INBOUND47\ASPNET'

I have installed a copy of SQL Server 2005 on my local machine temporarily so we can re-configure our SQL server machine from acratch.  I am trying to get it to run from other machines, but I am having problems.  if I run my page from Web Developer Express, it works fine, but when I try to access it from the standard web browser using my machine name, it gives me

System.Data.SqlClient.SqlException: Login failed for user 'INBOUND47\ASPNET'

My web.config file looks like this:

<configuration>

	<!-- enable forms authentication -->
	<connectionStrings>
  <add name="AIMIntranetConnectionString" connectionString="Data Source=INBOUND47\AIMCCSWEB;Initial Catalog=AIMIntranet;Integrated Security=True;user ID=aspnet;password=sss"
   providerName="System.Data.SqlClient" />
 </connectionStrings>
 <system.web>
		<authentication mode="Forms">
			<forms name="ASP101SampleAuth" loginUrl="login_db.aspx" />
		</authentication>
	</system.web>

	<!-- set secure page to reject anonymous users -->
	<location path="admin.aspx">
		<system.web>
			<authorization>
				<deny users="?" />
			</authorization>
		</system.web>
	</location>

</configuration>

I did do as one user suggested and add aspnet to my users, but that did not work.

Any and all help is appreciated.
