Node triggered a down alert but node was up

I'm looking to figure out why an alert was triggered on a node stating that the node was down but the node was up.  It's a Windows server and we polled this node via WMI and ICMP.

Anyone else ever have this happen?

We have had similar issues in the past.  I found that resetting the performance counters solved the problem.  Use an elevated command prompt, cd to windows\system32 and issue a lodctr /R command.  Do the same in window\syswow64.  Next, issue a WINMGMT.EXE /RESYNCPERF command, then reboot.

I just started looking for answers to this same question. I'm new to SolarWinds. We have a number of nodes in our environment triggering this alert. I'm able to ping the device in question from the polling engine, which is strange because failure of ICMP is supposed to be how this alert is triggered. I'll circle back here if I find some useful information.
