Enable TLS 1.2 on Laserfiche 11 on a Server 2012 R2 system

replied on March 20, 2023

Windows 2012 can be configured to support TLS 1.2, so what you want is possible. One question is if the steps in that document are a viable way to achieve your goal. If the document describes itself as a guide for Win 2016, I'm sure the authors didn't try it on Win 2012.

What I didn't see mentioned in the document was any mention of configuration of client machines and applications, which might be necessary depending on your version. But, "We do NOT have access to any of our Laserfiche websites now" implies to me that the configuration went wrong on the server side; all modern browsers should be capable of connecting over TLS 1.2.

Most likely a number of Windows Server 2012 R2 features (including but not limited to RDP) were still configured to use TLS 1.0/1.1, and when those protocol versions were disabled at the OS level, a bunch of things stopped working.

When I've accidentally locked myself this way before, I was able to re-enable TLS 1.0/1.1 on the affected machine using remote registry editing (see below) or PowerShell remoting.
