Trying to get a windows 2008 R2 server to the latest PCI standards, which require disabling of TLS 1.0
FTPS stops working once TLS 1.0 is disabled. TLS 1.1 and 1.2 are enabled and all other SSL items (RDP and websites) are working using TLS 1.1 or 1.2 correctly.
Our clients use Core FTP to FTPS to the server (since this appears to be the only FTP software that worked stably with FTPS)
234 AUTH command ok. Expecting TLS Negotiation. TLSv1, cipher TLSv1/SSLv3 (RC4-MD5) - 128 bit
is Core FTP connecting to our server with TLS 1.0 enabled. Once disabled and server rebooted, a connection cannot be established to the server at all.
There doesn't appear to be anywhere in CoreFTP or IIS 7.5 to set which versions of TLS to use. All settings for PCI have been changing using the crypto tool to ensure they are correct.
Any suggestions, or is this another issue with Microsoft products simply not working without TLS 1.0 or SSLv3?
