[jcifs] help! parse the ORPC protocol

[Xiaobo Li]

hi all
	Is there anybody familiar with ORPC? I want to ask some questions.

	I uses Ethereal to observe the traffic of a DCOM request.
The dcom version is 5.6 (Win2000).
The interface is IRemUnknown2, opnum is 5, I think it should be 
HRESULT RemRelease (
		 [in] uint16 cInterfaceRefs,
		 [in, size_is(cInterfaceRefs)] REMINTERFACEREF InterfaceRefs[]
		);

 And the stub is as follows.

05 00	major version
06 00	minor version
00 00 00 00		flag
00 00 00 00 	reserved
6c d2 48 a3 c4 ed 2b 40 9e cf 7a dc 84 01 5b 77		CID
00 00 00 00		no extensions

//OPCTHIS end

01 00 00 00     
01 00 00 00
03 bc 00 00 04 08 0c 08 b3 0e ad b3 66 a2 8d 20      IPID
05 00 00 00     cPublicRefs
00 00 00 00     cPrivateRefs
00 00 00 00

In fact, I can only understand the content till the OPCTHIS.
What effect do other bytes take?
Is there any body can teach me?
thanks in advance..
