NI Network Browser Error

[ackatharotiya]

Hello! Folks,

I've LabVIEW application that monitor network opc tags. This application was working so far in the past and all in sudden stopped working. Basically it throws an error as attached image. I made sure that my DCOM settings are intact and there is no windows update happened on the machine. I searched online on every forum but couldn't find solution to it. 

If you guys can guide me on this would be helpful. Thanks!

It's either Hardware, Software, or Network.

You haven't told us about your Hardware.  You haven't posted (so we can examine) your Software (LabVIEW Program).  We have no idea about your Network, specifically what "rules" are in place, and what security procedures (possibly outside your control) are allowing access to Network resources.

If I had to guess (and with the information you provide, "guess" is all I can do), I'd "guess" that the most likely change is the Network, a change in access policy that may have been "pushed" to your machine.

Thanks Bob for a quick reply. As the application is only in EXE format I couldn't post the code. As for the network, I'm really not sure what security procedures and rules are deployed in the network. But your guess would make sense. And I'd involve IT to see if there is any change in access policy pushed for my application.

Thanks again!
