• Adding a linked MS-Access database to SQL Server 2008 r2, 64-bit

  Update: besides using msdasql, it works, in some cases, to do the following before creating the linked server:
  right-click and select "properties" for "Microsoft.ACE.OLEDB.12.0" under Server objects, Linked servers, Providers in SSMS. Check "nested queries" and "allow inprocess." Then create the linked server for access accdb using the ACE.OLEDB.12.0 provider, with the full access acccdb path and filename under data source.

• Troubleshooting Orphaned Users - When migrating from one SQL server installation to another, the databases keep their users, but the connection between the SQL server login and the user in the database gets broken. This is referred to as an "Orphaned User", and it can easily be resolved here.

1 Praise the Lord.

Blessed is the man who fears the Lord,
who finds great delight in his commands.

Psalm 112:1, NLT

16 "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.17 For God did not send his Son into the world to condemn the world, but to save the world through him.18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.19 This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil.20 Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed.

21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."

John 3:16-21

17 You may say to yourself, "My power and the strength of my hands have produced this wealth for me."

18 But remember the Lord your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your forefathers, as it is today.

19 If you ever forget the Lord your God and follow other gods and worship and bow down to them, I testify against you today that you will surely be destroyed.

Deut. 8:17-19
