Netpath error "No data found"

orionfan Dec 14, 2017 2:07 PM

We have been using Netpath since it came out, and it has worked very well for us until recently. Two weeks ago, we had our normal Windows patching weekend. A couple of days later, I discoverd that all of our Netpath probes were no longer displaying in NPM. All of them have the following error:

No Data Found

Netpath has no data about this time interval. If this happens often, consider increasing the probing interval by 5 or 10 minutes.

We have almost 20 Netpath servers that stopped working. I have reinstalled the agent on one of our Netpath servers. I also rebooted our main poller and it started to display Netpath data, but it stopped eventually. Today I rebooted it and the amount of time displayed was even shorter before all of them stopped showing data in NPM.

I do have a case open on this, but that almost two weeks ago so I'm looking to see if anyone else has any recommendations.

After several weeks with support, I started looking at this myself. I discovered that there was a Windows Update (KB4049017) that was installed which is a security rollup for .NET. I uninstalled the update, rebooted, and the Netpath probes started working. I have updated my case with Solarwinds with what I found. Hopefully they can test this and either do a hot fix or make sure the next version works with this KB. Also, KB4049017 was installed as KB404177. It looks like there are variances of KB4049017 based on server OS.

  Curious, how did you know it was this particular KB?
  I'm running into the same problem. I have a netpath assigned for our internal OWA URL to 3 different probes (all solarwinds servers actually) in 3 different data centers
  Netpath only returns data on one of the servers, the other two are seeing the "no data found" error. I don't see KB4049017 or KB404177 on any of them. Though I do see KB4041777 on all 3
  I can tracert to the URL from the servers where netpath isnt working so I'm not sure whats going on.

    Hi Ryan,
    
    I knew it was this particular KB because once I uninstalled this KB and rebooted, Netpath started reporting correctly. The other reason I started looking at Windows Updates is the issue started shortly after one of our Windows patching weekends.

  I am also having the same issue. It was working in version 12.0.1 and after I updated to 12.2, netpath no longer works. I dont have the above patches on my system and the ports are open on my firewall. I able to run a ping and traceroute from the server. I have had no help from support.

    I've currently got a case open with support as well, this seems like an escalating issue. He suggested that TLS is off on the servers where its not working, however upon looking at the server where it is working TLS is also off on that one, so I don't think solarwinds has a good handle on the root cause yet.

Got this from support:

Error While importing node XXXX Details: Network access for Distributed Transaction Manager (MSDTC) has been disabled - …

This resolved my issues with netpath!! (ignore the fact that the article doesn't mention netpath at all)
