I am trying to access the VISA resources on one cRIO from another, and despite everything I've tried I get the error:
Error -1073807192 occurred at VISA Open in visa test.vi
Possible reason(s):
VISA: (Hex 0xBFFF00A8) Access to the resource or remote machine is denied. This is due to lack of sufficient privileges for the current user or machine.
I installed VISA Server on the cRIO I'm trying to access and VISA Remote Passport on the client (I actually went ahead and installed VISA everything on both just to check). I went into VISA server settings on the cRIO I want to act as a server and explicitly added the client's IP address, I also added * just to be safe, but the error persists.
I have no issue accessing the remote resource via VISA Remote Passport from my PC, I just cannot do it from a cRIO. Stranger still, I cannot access a local VISA resource through VISA remote passport.
192.168.1.203 is my desktop
192.168.1.202 is the server cRIO
192.168.1.99 is the client cRIO
In VISA server settings on the server, I gave access to 192.168.1.99, 192.168.1.202, and *. The following code returns the error when run on either the client or the server cRIO, but successfully opens the resource when run from my Desktop
I also tried to get the cRIO to access anything using the remote URLs (COM ports on my PC etc.). Every target I tried to access I added the cRIO's IP and * in the Server settings (and saved them). I have no issues accessing any remote resources from my PC.
Both cRIOs are running CompactRIO 17.0. I tested with CompactRIO 15 in case it was a recent issue, but I had the same problem.
Am I missing something?
Solved! Go to Solution.

I added a 3rd cRIO to the mix, this one a 9012, and it is able to successfully access VISA resources on the 9030s. So I can successfully use VISA Remote Passport on everything but the 9030s.

My coworker may have found the cause:

I'm going to try out the recommended fix.
