[AccessD] ADP Connection Problems

I have a legacy database Discipline.adp in Access XP connection to a SQL
2000 database.  On one particular computer, the database will not connect.
It gives me a runtime error 76 then tells me to go to File> Connect and
change the connection parameters.  If I try to open that, it just gives me
the same error and message. 

I can make an ODBC connection to that same database on that machine.  

I also tried making a new .adp database and making the connection there.  It
immediately gives me the same error and message and no way to get to that
menu.

I have already un-installed and re-installed Access, and still get the same
problem.

Does anyone have any ideas about how to fix this?  I am going for a re-image
on Monday if nothing else works.
