I'm running a recently installed LDMS 2016.3 core on Win2012 R2. I'm just starting migration, so there are less than 100 nodes on it right now. About once a week, all of my agents will fail a vulscan with a message about unable to contact host. I can sometimes fix it by logging into the core and running IISRESET, or for a bit of a longer fix I can reboot the server. I work in an environment that is secured to NIST standards, so IIS has been "locked down". Is there a set of recommended settings I can compare my IIS and .NET to? Are there other suggestions on where to look for what's causing the problem?
My older LDMS 9.6 core does the same thing from time to time.
