Hi,
How is it possible to use trusted connection for an Intranet site?
Intranet is using a webservice which is hosted on a web server on LAN.

This is the connectionstring that I am currently using for the intranet website in the company LAN.
<value>Data Source=SQLMachineName1\MSQL_DEV;Initial Catalog=DBdatabaseName;Persist Security Info=True;User Id=WebUserAccountName;Password=password;</value>


I would like to use this connectionstring instead so that I can have more control over the logged in users.
If I do use this connectionstring the error it gives is:
Login failed for user (null). Not associated with a trusted sql server connection.
<value>Data Source=SQLMachineName1\MSQL_DEV;Initial Catalog=DBdatabaseName;Integrated Security=True</value>
