I was hoping it wouldn't come to this. I'll have to be honest that
FileZilla has caused me a few nightmares in the past in regards to
connecting to FTPS servers running on IIS. While FileZilla does
advertise FTPS support, it really depends on the server (as you
described in your own experience) that you are connecting to.

In my case, FileZilla refused to establish a secured connection the
FTPS server. In the end I had to modify the cipher suites on the IIS
server because the FileZilla developers were adamant on not altering
their code to work with what they considered a faulty FTPS
implementation. I believe the issue dealt with the IIS server using
what the RFC indicated was an optional component of FTPS. Since
FileZilla didn't implement this particular option, the IIS server
refused to establish a connection when it should have if it was truly
compliant to the standard.

100% the fault of Microsoft. I don't blame the FileZilla developers at
all, they seem very dedicated to the idea of following established
standards and I back them completely. I even agree with their
reluctance to add PKI certificate validation.
