unknown RPC opcodes during join+logon

[Vijay Kota]

I am attaching the traces for 2 clients - FUBAR and FOOBAR.

Here's what my Win2K clients do (pl. refer to trace):
	Odd name: <8-byte-credential><4-byte flags = 0x6007ffff>
	Even name: <8-byte-credential>,0x6B,0,<4-byte flags =
0x0007ffff>

But here are the results I got with changes to Samba:
	Odd name: <credential><4-byte flags = 0x0007ffff>: Access Denied
	Even name: <credential>,0x6B,0,<flags=0x0007ffff>: Access Denied
	Odd name: <credential><flags = 0x000001ff>:
		Success but "servicePrincipalName" attribute in Active
		Directory disappears
	Even name: <credential>,0x6B,0,<flags=0x000001ff>:
		Success but "servicePrincipalName" attribute in Active
		Directory disappears
	Odd/even name: <credential>,0x6B,0,0x6B,0,<flags=0x0007ffff>
		Everything seems ok. However I think Luke is most
		probably right about the PDC ignoring the flag value -
at
		least part of it. I haven't tried diff. flag settings

Hope this helps,
Vijay

Are you sure it is not simply padding? Any mention of even vs odd
NetBIOS 
names makes me think of padding.

Can you extract the relevant packets and post them to us?
