Hello,

	We work on the Openchange Project
	Openchange intends to provide an Open-Source implementation of Microsoft
	Exchange Server 2003 under Unix Platforms.

	I work on the Openchange Part and hard for Stub data after
	Bind & Bind Ack on the port mapper 135 between a Exchange server
	and a outlook client.

see below the 132 bytes

I have identifers some parts of this, but many things remain fuzzy.

I would like to gather informations of people who worked above to advance
more quickly and to be able to divide it.

Thks for your suggestions.
