We've been mandated to disable TLS 1.0 (and 1.1) on our Windows 2008 Server R2 boxes. When we do so, we get this error:
Exception type: COMException
Exception message: [Microsoft][ODBC SQL Server Driver][DBNETLIB]SSL Security error
at WebFarm.SessionManagerClass.ReadSessionData(String GUID)
when connecting over MSDTC from the IIS 7.5 server to the SQL Server 10.50.6542. The SQL Server has been updated to support TLS 1.2.
I have tried disabling XA transactions, which changes where in the connection process it fails, and which COM+ exception appears. When Enable XA transactions is checked, we get
Exception type: COMException
Exception message: Retrieving the COM class factory for component with CLSID {8443511D-50D9-11D4-B73C-0080C8898838} failed due to the following error: 80004005 Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL)).
at PHSCC.DCP.BMP.Source.Util.UseWebFarm.SaveFullSession()
Enabled or disabling SNA LU 6.2 transactions has no effect
Any suggestions or experience?
thank you, Jon Angel and Saranya Rao
