Security Protocols

[Sven W]

Hi,

I have two Windows 2016 Servers with IIS installed. Same Patchlevel, same .Net Framework. Registry has no additional configuration at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

Server 1:

PS C:\Windows\system32> [System.Net.ServicePointManager]::SecurityProtocol
Ssl3, Tls

Server 2:

PS C:\Windows\system32> [System.Net.ServicePointManager]::SecurityProtocol
Tls, Tls11, Tls12


What can be the cause for the differing config? I want Server 1 to be configured as Server 2, although I do not see any differences.

Thanks

Sven
