Hi Pertti,

ASP.NET applications run un the ASPNET account even though the server has someone else logged in. You can change your connection string to include the username and password and remove Integrated Security or you can impersontate a user on your system. ASP.NET will then use that user instead of the ASPNET account. The thrid option is to grant rights to the ASPNET account.

I wonder why it is saying specifically that "Login failed for user 'MAIN\ASPNET'.", when my Windows XP username and password are something totally different? I tried SQL server authentication, as well, but to no avail. Can't figure it out, elemental as it might be.
