SSL client/server communication

[Matt Nunnally]

I'm trying to build a client for a third party application that resides on the server and accepts SSL communication. i'm using this code:

tcpClient.Conne ct(m_IPAddress, m_Port)

Dim sslStream As New SslStream(tcpCl ient.GetStream, False, New Net.Security.Re moteCertificate ValidationCallb ack(AddressOf ValidateServerC ertificate))

sslStream.Authe nticateAsClient (m_IPAddress)

If sslStream.CanWr ite And sslStream.CanRe ad Then
Dim bytes(tcpClient .ReceiveBufferS ize) As Byte
Dim sendBytes As [Byte]() = Encoding.ASCII. GetBytes(XMLStr eam)
sslStream.ReadT imeout = m_Timeout * 1000
sslStream.Write (sendBytes, 0, sendBytes.Lengt h)
sslStream.Read( bytes, 0, CInt(tcpClient. ReceiveBufferSi ze))
SSLSend = Encoding.ASCII. GetString(bytes )
Else
If Not sslStream.CanRe ad Then
tcpClient.Close ()
SSLSend = "0"
Else
If Not sslStream.CanWr ite Then
tcpClient.Close ()
SSLSend = "0"
End If
End If
End If

On the authenticate as client, I get an exception: A call to SSPI failed, see inner exception. Is the code I have correct? Is this a server problem?

What is the inner exception?
It will probably contain more insight onto the problem.

[Matt Nunnally]

It says "cannot obtain value".

[Plater]

I am assuming that the underlying exception's message is "cannot obtain value"
and not that when you try to look at the underlying exception it tells you it cannot see it?

[Matt Nunnally]

I'm sorry. It says '"The Local Security Authority cannot be located"

[Plater]

I'm sorry. It says '"The Local Security Authority cannot be located"

hmm, well that's LSASS(.exe). Do you have all that stuff running on that system?

[Matt Nunnally]

Yes. It the lsass.exe is running
