Here are my connection strings.
  <add name="core" connectionString="Data Source=.\SQLEXPRESS;user id=xxx;password=yyy;Initial Catalog=tecore_Core"/>
  <add name="master" connectionString="Data Source=.\SQLEXPRESS;user id=xxx;password=yyy;Initial Catalog=tecore_Master"/>
  <add name="web" connectionString="Data Source=.\SQLEXPRESS;user id=xxx;password=yyy;Initial Catalog=tecore_Web"/>

try using 'local' instead of the . on my local installs I actually have named installs such as SQL2005, SQL2008, etc... When you installed did you install it as "default"? If so then simply use "Data Source=local;..."

The original connection string used localhost.  I changed it to local and still getting the same error screen.  Thank you.

Hi,

What is the name of your Sql Instance?

Let's say you go into Microsoft SQL Server Management Studio, this would be the upper menu level item name.

Then modify your connection strings using this name as follow :

  <add name="core" connectionString="Data Source=SqlInstanceName;user id=xxx;password=yyy;Initial Catalog=tecore_Core"/>
  <add name="master" connectionString="Data Source=SqlInstanceName;user id=xxx;password=yyy;Initial Catalog=tecore_Master"/>
  <add name="web" connectionString="Data Source=SqlInstanceName;user id=xxx;password=yyy;Initial Catalog=tecore_Web"/>  

Replace SqlInstanceName with your name, it can be something like YourName\SQLEXPRESS, just put everything you see in uppercase.

Apparently I instlled it as a named instance.  I had to put macineName\sqlName in connection string to make it work.  It won't work with local when it's a named instance.  Thank you.
