Hi Ronnie,

I am sure you will be able to resolve our issue. Thanks for
replying in such detail. I will read this and suitably reply.

Thanks once again.

What are you planning to do?
Your question seems to indicate you want to build a freestanding
dce/rpc implementation, something that is impossible with the ethereal
code.

Yes, ethereal does contain dce/rpc code, lots of it.
However, the problemspace ethereal faces is vastly different from a
freestanding dce implementation, thus the dce support in ethereal is
factored to only address the very limited requirements of ethereal.
The ethereal dce implementation is a very reduced functionality
implementation that is focused on ONLY providing unmarshalling of data
and nothing else.
It does this quite well however, but a full implementation of dce
mandates a completely different implementation.

Full dce and runtime is a major undertaking, I estimate it would take
for someone good and very experienced in dce about 2 man years to
build.
20+ manyears if the implementors are not very good or not familiar with dce.
Compare this with the adapted-to-ethereals-problem-space
implementation of base dce that only took ~6 man months all in all to
write.
including a whole bunch of actual dce interfaces/protocols.


Ethereals dce source code can be used to implement a dce dissector for
etheral, no more no less. If you want to do anything beyond building a
dce-interface dissector for ethereal, the source code for dce in
ethereal is of no use for you.


please qualify your question: 
exactly what do you want do do with the soucecode in ethereal for DCE?
1,  build a dissector for a dce interface for ethereal? yes that is easy.
2,  build a dce runtime and environment to interact in a dce
environment? no that is impossible.

Ethereal sourcecode for dce is complete enough for ethereal
unmarshalling-only use and can even handle full pointers properly,
smething which not even MS implementation can do.
But it is factored and limited in such a way that any use beyond that
is impossible.


If you want a full freestanding dce implementation   that actually
talks and interacts in a dce environment it is better to start from
scratch.
(yes, Guy mentioned the now released full implementation from
TheOpenGroup but if you look at that code that is designed by committe
  it is still quicker to start from scratch and probably better
quality as well unless your developers have suboptimal experience)
((my brain is still hurting from looking briefly at the DCE code from
them a few years ago))
