Mas200 4.4 (yes, we are updating now) client running on Win7 64 machine.  When I run a VI import job on my machine I have no problems.  When I try to run the same job on the problem machine the job fails with the message above.  Same Windows logon (domain admin), same MAS logon (admin).  I also notice that when I open the job in VI Import Job Maintenance on a good machine the dsn name appears in the Data Source drop-down on the Configuration tab.  On the problem machine the Data Source dropdown is blank and it does not list any of the system dsn names that are defined on the machine.  It seems like a security issue on the problem machine, but I am stumped.  Any help is appreciated.
