able to ping ip but node shows down

I'm able to ping this ip from any pc both inside and outside my network.

But can you trace to it from your polling engine box?

I had this issue and found that I could not ping the device from my solarwinds box but could from my pc. After I found the issue and corrected it then everything was fine. do a ping or traceroute from your solarwinds box and I believe you will find the issue

Tracert from Orion box is fine all the way back to their ISP.   Two hops 'request timed out' but it does complete.

Why would an ICMP node show down but I'm able to ping the IP from the same box as Orion NPM?

can you provide the traceroute from your NPM box? Something does not sound correct. have you tried deleting the node and then readding it?

Node:

    66.224.33.58        0047_Txxxxxxxxxxxxxxxxxx_66.224.33.58_2007047115    No response    No response        100 %

From the same box as Orion NPM.

Trace complete.

In the original post:  Node deleted and recreated. 

See if this thread helps you out.

That worked.

I had nothing in the data portion so I added a 10 which increased it by two bytes.

Increased the ICMP timeout to 5000 miliseconds.

Node came up.

Thanks for finding that.

Removing and then re adding worked for me - it did a rediscover and it came back online
