How can I ASPX connect to SQL 2008 in another IP via Windows authorization?

Is it possible to connect to the same database in different windows by IP? I want to connect using Windows authorization, not by username and password.

Configuration for the local connection to my database:

<add name="connectionString" connectionString="Integrated Security=SSPI;Persist Security Inf开发者_如何转开发o=False;Initial Catalog=ViaMura;Data Source=.\SQL2008" providerName="System.Data.SqlClient"/>

Assuming the proper ports are open, yes. The credentials are transmitted via NTLM authentication, I think.
