Network Device appears and can be queried in MAX but doesn't appear as VISA resource in labview

[TheWolfmansBrother]

This just occurred and had been working fine before (at least a year). I have a Keysight DSOX6004A Scope, it is connected to my PXI chassis through LAN connection. The scope shows up in MAX under Network Devices, and I can open the test panels, query the scope and it responds without error (*IDN?/). In Labview for the niScope Initialize.vi, I had been using a visa resource constant with "Scope" selected from the dropdown. It used to work, now "Scope" is greyed out and there are no devices listed in the dropdown to choose from. Nothing appears when I refresh or select browse. This is in a built executable and had been working for some time, I don't want to have to rebuild the program or really make any changes to it since it is a released test program. I attempted to change the name of the device in MAX, but it still won't show up in the resource dropdown. I thought about deleting all of the devices and re adding them all but there are 15 other devices, so that would suck.

anyone have any ideas on what might have changed that i can get the scope showing back up again?

Thanks.

 niScope Initialize.vi as the prefix suggests works only with NI's Scopes and not Keysight's scope.

In NI MAX, please check the Alias for the NI Scope that you named as "Scope"

Ok so I'm an idiot, and should probably go have another coffee to wake up. There is supposed to be an NI5162 scope card installed in the chassis, its' not. It was probably pulled for calibration or something. Has been a long time since I messed with this station, and immediately just thought I was trying to reference the Keysight scope. I also sort of fell into productions "dumb bubble" when they told me the scope wasn't communicating with the station.
