On my first system there is a sql server database on which the library application based and worked properly. But the second system is a Windows Server 2008. And I have developed another Student Management project , which had installed in this server and work correctly.But I want the server should use my sql database as well as the Library database of the first system.

Refer to connectionstrings.com for what it should look like. But it's pretty easy, use the ip address if the name won't resolve.

are the databases in the same server?
if no. Have the users the same priviliges?

1. You need to reply to comments so that the user is notified. I was not notified, I happened to come back and look.
2. You have to provide the right information on how one machine can connect to the other. It is really that simple.
