Access denied: This host computer's IP address is not on the target's allowable access list.

Hello Everyone:

I was working normally with my CRIO NI9024 at my work. I went home and when i came back the other day. I tried to compile my working application.

The surprise was that i got a strange message "Access denied: This host computer's IP address is not on the target's allowable access list.".  Now, i can not connect to my CRIO device. I tried to reset all IP adresses , in the CRIO and in my PC machine. What can i do????.

Hi!

This sounds strange...you haven't did any change, right?

Please format the controller, and after try to connect again!

Yes. That was the solution. I had to uninstall the NI-RIO software on the target. I uninstall everything on the CRIO. then, I install the software again, but i also had to re program the fpga, the host and the target. And i reset also my IP, on the measure and automatition software. I found a big bug i guess.

Thank's anyway. Love National Instrument. Hope to work there someday.

I am having a similar problem on my cRIO-9075 but without success in solving the issue.  I have uninstalled everything from the cRIO, reinstalled and reprogrammed.  I am unsure about what you mean by resetting the IP in the MAX. What I have found is by going into the ni-rt.ini file in the cRIO board and changing the RTTarget.IPAccess="" to RTTarget.IPAccess="+*" I can get everything running.  The problem is when I disconnect the code reverts back to RTTarget.IPAccess="". Any suggestions why this is happening or how I might fix it?

Thanks,

Brendan
