I am having issues with deploying agents to servers that have IIS installed. The initial install seems to complete without error. However, when I try to request an inventory scan/deploy software/etc., I get an error "The remote computer refused the network connection." I researched this error (including copying certificates from the Core, etc.), but didn't come up with anything.
The one commonality between all of these servers is IIS is hosting a website on the servers. When I check the Event Viewer log, I find about 7 errors each time I try to run the scan. The errors all point to "serviceHost.exe" with the faulting module "ntdll.dll."
I'm thinking there must be some permissions issues happening once IIS gets installed. Maybe some certificate conflicts? I've been researching, but I don't see this has been reported. Any help/recommendations would be appreciated.
