PETSHOP 3.0 The 'NT Authority / Network Service' error occurs when Windows 2003 is running. The reason is that this error will appear when connecting SQL Server using trust connection. In Windows XP, the run account of ASP.NET is ASPNET, but In Windows Server 2003, the run account is changed to Network Service, so the login is unsuccessful. The solution is: Enter the NetWork Service in the 'User' -> Add User -> Login name of the SQL Server Enterprise Manager, and it is imposed on the corresponding permissions.
