How to access a remote SQL Server database

As I mentioned in my previous post about "How to access SQL Server Database from ASP.NET Web Application Without Credentials", I just continued my research towards finding a better approach for enable the Windows Integration Authentication between Web Server (IIS) and SQL Server that exists in different network domain or remote server.

During this span of analysis, I found various new technical terms such as “Trust Domain”, “User Delegation”, ”Set SPN”, which are basically Windows Active Directory and Domain oriented changes that should be done by System Administrator. It seems an Asp.Net developer could not be done anything except specifying the domain account in Application Pool in IIS for that Application.

Having said, the analysis has taught me that it requires lot more changes from Server and Network part and could be a tedious job also. I posted in MSDN forum and got various valid references which helped me to proceed further.

Here are the references links:

Hope this helps to implement the technical changes according to your requirements.

Happy Learning!.
