Is there more data on this, or a guide on netpaths that I can access?
I am still working on this issue with SolarWinds support. The first thing they recommended was for us to add PUT and DELETE to -ExtensionlessUrlHandler-ISAPI-4.0_32bit
The newest info I have is this, which I have not done yet but it may be helpful if you have time to try it:
Comments on the page above provide some answers which makes sense to go over and test it on customer machine since it really seems to be related to IIS and machine config.
* check the application pool of "api2" app is running in "integrated" mode (basically everything is related just to "api2" sub application of Orion)
* try to enable PUT / DELETE verbs in "Request Filtering"
* check the webDAV is disabled/removed
As the NetPath Probe uses the SolarWinds Agent that is installed by default on the MPE when you first install SolarWinds, it might be worth removing and reinstalling the agent. I've seen instances where the agent doesn't install properly for some reason.
You could test it by installing a new probe on another machine first, and see if you can set up new NetPath services using that probe. If you can then 100% try reinstalling the MPE Agent/Probe. If it doesn't work, then oh well, nothing ventured nothing gained!
