Hello everyone, I am having an issue that I hope someone can help me out with. We're trying to do some hardening on some IIS servers in our DMZ. Currently we have a terminal server (2008 R2) in the DMZ that we use to remotely manage the IIS Servers, which
are running 2008 R2 Core.
I have KB3080079 installed on all of the servers so that RDP works correctly, but when I disable TLS 1.0 on either the TS, or the IIS erver (or both) I cannot use IIS Manager to remotely connect to the IIS server from the TS, I receive the following error:
Could not connect to the specified computer.
Details: The underlying connection was closed: An unexpected error occured on a receive.
If I cancel out of the error, and click on the server in IIS manager again, I get the following error:
There was an error when trying to connect. Do you want to retype your credentials and try again?
Details:
The client and server cannot communicate, because they do not possess a common algorithm.
I have exhausted my google-fu trying to find an answer to this, the closest was a thread in this forum started in March 2016 that said the OP was working with Microsoft to resolve, but of course, no resolution posted. Any help would be greatly appreciated,
thanks!
