MAX can't find any of the PXI hardware, but device mgr does.

[Andromeda]

We've got a PXI system which has developed a MAX configuration problem.

MAX cannot see any PXI hardware at all, although it's in the NiPAL report, and the device manager sees it.

Any ideas?

System configuration is:
PXI-6052E
PXI-6602
plus a bunch of SCXI boards

The system is physically 7000 miles away, but I can RDP into it.

Thanks,

You could try opening a command prompt and typing:

net start nidevldu

This starts the NI system service that monitors the system for NI hardware and launches the appropriate drivers and it is possible it somehow was disabled on your system.  If this command fixes the problem and your devices are then seen in MAX you need to run the following command to set the service to start automatically on bootup:

sc config nidevldu start= auto

If your problem was not fixed by the first command then try uninstalling NI-DAQ and MAX from the control panel and reinstall NI-DAQ (MAX will get reinstalled automatically by the DAQ installer).  This should clear all the register values and local databases associated with MAX and also reinstall required services.  Reinstalling will require a restart so hopefully your remote system doesn't get hung up during the reboot.

Thanks very much for your help!

As it turns out, the service starts, but fails. An error report (niswreg.txt) is produced, but it just contains the registry keys.

I'll see if I can un-install /re-install MAX over the (slow) RDP connection...

Thanks again.
