On the other day, I have created a new NAV database (2009 R2) using the SQL backup and when I try to access the database using the NAV client the following error popped up

But even after doing the setup I ran into the following

The reason behind it was that there exists two xp_ndo dll’s that are named xp_ndo and xp_ndo_x64. One should use xp_ndo_x64 for the 64 bit. So, I changed the reference in the stored procedure to xp_ndo_x64 but still encountered the same error. The solution is to always have the reference say xp_ndo. Therefore, I renamed xp_ndo to xp_ndo_x32 and xp_ndo_x64 to xp_ndo, and then I changed the reference in the stored procedure back to xp_ndo.
