There is a bug in TLS1.2 on FTP in 2008R2 and file uploads. It is the same issue in 2012 servers, but that has been addressed with a hotfix: http://support.microsoft.com/kb/2888853/en-us
However the hotfix only deals with the 2012 servers, and not the 2008R2 servers. Who do we contact to see if the hotfix can be extended backwards to cover 2008R2 servers?
The conditions to make this error occur are:
Set the server to use the TLS1.2 protocol, via registry \SCHANNEL\Protocols\... changes
via registry \SCHANNEL\Protocols
Use an FTP client to connect via FTPS and TLS1.2 (filezilla), and upload a file. It will fail with FTP error message: as described in the hotfix above.
How do I get some attention on this issue please? thanks
Please check this thread and the blog in it to troubleshoot:
File upload fails in FTP 7.5, getting error 550

I hope this helps.
Yes that first link is the same issue. The MS FTP is not finishing the connection correctly under TLS1.2 spec, which caused the upload to be deemed a failure.
The same fault also got carried through to server 2012, but they got a hot fix to solve the issue. (support.microsoft.com/kb/2888853)
I'd like to somehow get the same fault fixed in 2008R2, if possible. How do we do that please?
