When configuring FTPS in BizTalk Server 2010, there is an error "The client and server cannot communicate, because they do not possess a common algorithm"


Problem Description

==================

 

When configuring the new feature FTPS adapter (receive or send) to connect FTP server in BizTalk Server 2010, there may raise the following error in the event log on BizTalk Server:

 

“The client and server cannot communicate, because they do not possess a common algorithm”

 

Problem Analysis

================

 

We collect dump files forBTSNTSvc.exe when reproducing this issue, and we have the following information.

 

The status code 0x80090331 means SEC_E_ALGORITHM_MISMATCH.

 

In addition, after we look into the source code, from the parameters which was passed to sspicli!AcquireCredentialsHandleW by the BizTalk xceedftpbiztalk module, we could see BizTalk FTPS only support TLS v1. So the problem is caused by that TLS v1 is disabled in the BizTalk Server box.

Problem Resolution

=================

 

Please check the following registry key in your BizTalk Server box to see if there is any TLS v1 registry key been disabled, that means the value is 0. If so, please change the TLS 1.0 Client registry key value to 1, that enable TLS 1.0 for client.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS1.0\Client
