Hello there,

I have an app that connects to a Server (running on remote machine,
server is written in TCL) with TLS, all works fine under Windows XP but
if i use the App under Windows Vista it doesnt works.

It raises an Exception on:

s.AuthenticateAsClient(server, Nothing, SslProtocols.Tls, False)

that a call to SSPI (or smt like that, dont have vista around here atm)
cant be done, coz it doesnt get a connection to this Service.

Validation is done by:

Public Function ValidateServerCertificate(...) As Boolean
Return True
End Function

(dont forgot under XP it works fine)

using Visual Studio 2005 SP1

thanks for help, greets ProlyX
