"SQL Server does not exist or access denied" error message

Hello!

When I start my .aspx with ASP.NET Web Matrix Server, it work, but when i try to start it with IIS I get error message.

TIA,

Misha

What is your connection string to the database like? Are you using a trusted connection? Is IIS running under a different account than Web Matrix? SQL Server needs to know about which accounts are acceptable.

|||string ConnectionString = "server=SERVER;database=pubs;trusted_connection=true";
SQL is on server PC, Web Matrix on Workstation.
