I guess the more important questions are:
On named pipes: do both SMB session key and SystemLibraryDTC work or just SystemLibraryDTC?

Pardon my questions, I am trying to understand the issue here. :)
Also, no need for new traces yet. First let me understand the issue. :)

it is the same with TCP/IP, SystemLibraryDTC is used as the session key or a sealed connectoin. Should I send you traces for that? I can do that tomorrow morning (CEST time) ...
