Not sure if this is the right forum but I am having a problem.

In VS 2013 I can see my sql server in SQL Server object explorer. It appears as :

MY-PC (SQL Server 10.0.4000 - sa)
MY-PC (SQL Server 10.0.4000 - MY-PC\Me)

There are other SQL Servers listed as well.

The problem I am having is that when I try to create an entity data model I have to enter a new connection. I choose Microsoft SQL Server as my datasource then from the Server name drop down I can only see "MY-PC\SQL Express".

It's been a while since I have touched VS or done coding so forgive me for being rusty.
Any ideas what is happening?
