ADO Error%3A 0x80004005

Question

I am in process of converting code writen in Labview 8.2 to Labview2013, and also changing from Windows XP to Windows 7.  I've been able to successfully compile & rebuild the code, but now am getting error message when running the executable.  Any ideas of how to resolve these?  
Here are the error messages I get:
NI_Database_API.lvlibB Tools Open Connec
(String).vi->NI_Database_API.lvlibB Tools Open Connec
(Path).vi->Titan_DBConnect.vi->TMS_frontend_Titan.vi<ERR>ADO Error:
0x80004005
Exception occured in Microsoft OLE DB Provider for ODBC
Drivers: General error: Invalid file dsn '' in NI_Database_API.lvlibB Tools
Open Connec (String).vi->NI_Database_API.lvlibB Tools Open Connec
(Path).vi->Titan_DBConnect.vi->TMS_frontend_Titan.vi-2147467259 -
There is a "Titan DBConnect.vi" VI that points to a "Database.dsn" file. 
Here is what is in the Database.dsn file:  (This file is created by Windows, and is the same for XP & 7.)
[ODBC]
DRIVER=Driver do Microsoft Access
(*.mdb)
UID=admin
UserCommitSync=Yes
Threads=3
SafeTransactions=0
PageTimeout=5

FIL=MS

DefaultDir=C:\Test Config
DBQ=C:\Test
Config\Database.mdb
Thanks!

The document you linked above definitely could be useful in resolving your issue. Your original error mentioned a .dsn file, and your second post mentioned a .udl file. LabVIEW communicates with the database through either the ODBC standard (uses a DSN) or the OLE DB standard (uses a UDL file). Which standard are you actually trying to use? Either way, make sure all the the settings you're using are consistent whichever standard you're trying to use.
http://digital.ni.com/public.nsf/allkb/1D5EB4DCBD13106486256B9D005E11B0 (the one you linked above) gives a good description of how to use the OLE DB standard to communicate with a database.
I'm also a little unclear whether you were able to test the steps outlined in the first document linked above (http://digital.ni.com/public.nsf/allkb/E7984C0DA0F0E65086257694005B4CB7). Let me know if that process was successful or if you ran into any problems trying to follow those steps.
You also asked a question about .mdb files. It may be possible that copying the file from XP to Windows 7 could have caused your problem. You can create a new .mdb file through LabVIEW by following the instructions detailed in this document:http://digital.ni.com/public.nsf/allkb/95EE6A951D01CE0A8625733F00098371?OpenDocument
Finally, when executing the above instructions that you quoted, make sure that the file path is correct and that you are pointing to a .udl file. I was unable to duplicate the problem you were experiencing with those steps on my machine.
Let us know if you make in progress with these suggestions.
