I can't see any services under the above tab in the console.
I have found this document which describes the issue we are having but the steps do not fix my issue: Unable to enable ANY service under "Self-electing subnet services"
I have found that the IIS Admin service will not start on the Core server which I am guessing may be the problem for us.
Looking at the errors and doing some research it seems that a previous issue we have had on the server may be casuing this problem.
We had to raise a call with Support as we could not login to the console and it was found that there was a problem with the IIS certificate. The support engineer recreated a new certificate which got us working again but since then the IIS admin service will not start.
Solutions on the web state to uninstall IIS and re-install it.
Can I do this on the Core server without breaking anything more?
