  2. Open SQL Server Management Studio and connect to your Database Engine.
  3. Browse to Security and click on Logins.
  4. Make sure you have NT AUTHORITY\NETWORK SERVICE in the list, if not then you will have to add it.
  5. Right Click on NT AUTHORITY\NETWORK SERVICE and click Properties.
  6. In User Mapping make sure MBAM Recovery and Hardware DB is checked and it has dbo and public role membership.
  7. Restart the SQL Server Services.

UDP port 1434 might be required for the SQL Serve Brower Service when you are using named instances. Check that no firewall is blocking UDP traffic to port 1434.
