I failed to indicate what this request is regarding. The request I am working on is for your question:
"MS-SMB section 2.2.8 says that FILE_OPEN_BY_FILE_ID should return STATUS_NOT_SUPPORTED. We have found that win2008 returns STATUS_OK for this bit. Can you please tell us how this bit works?
We similarly noticed that w2008 returns the NT_STATUS_OK for each of the following bits:
all of which are not documented in the current WSPP docs. Please clarify this behaviour, and if w2008 is not just ignoring these bits then please document what they mean.
Please also tell us what the differences are for handling these bits between the SMB and SMB2 protocols. We have noticed (for example) that the w2008 SMB2 server returns STATUS_NOT_SUPPORTED for bit 0x00100000 in the create options, whereas the same server using the SMB protocol returns STATUS_OK, and the SMB2 documentation says it should return STATUS_INVALID_PARAMETER.
You indicated that WIN2008 will return STATUS_OK in response to a SMB_COM_NT_CREATE_ANDX when the CreateOptions are set to FILE_OPEN_BY_FILE_ID.
My review of the source code indicates that WIN2008 will return STATUS_NOT_SUPPORTED. Would it be possible for you to obtain a network trace of the behavior you are describing?
In the meantime, I will continue researching the rest of your request.
