PCI 6503 self test error

Hi,
   I have some PCI-6503 boards and I need to install them in PCs with WinXP to use it with traditional NI-DAQ and SCXI-1000 chassis.

The boards are Ok , but i can understand why, in some PC, when I try to make a self test with traditional DAQ in MAX , I get a "The device did not pass the test" error. (with DAQmx the self test is passed without any errors)
Having a look at the detailed error, it is a -10461 resourceReservedError, but there is no application or nothing else that can reserve the board. Is a brand new XP installation.
Any Idea on how to solve?

thank you so much.
