Hi Volker

Yes, my question is if it's possible to do RAP over SMB2.

Do you know when Windows are dropping the support of RAP?  Where can I
find the related information?

Guessing from the subject: I really doubt that RAP is still
supported over SMB2. You will have to do DCERPC sooner or
later, I just heard a couple of days ago that the Windows
client code does not do RAP at all anymore in latest Windows
