Hi Volker, I'll be helping you with this issue.
Will get back to you as soon as I have questions or answers. Thanks!

Hi! While investigating oplocks I wrote a little test leading to the attached trace, which surprised me a bit. This test is running against Windows 2012 server. In frame 56 I get an exclusive oplock. In frame 57 I try to open the file a second time on a different connection, asking for an exclusive oplock again, create disposition as OPEN_IF. Frame 60 is the expected break response, breaking to level2. This break response is not replied to immediately. In frame 63 I try to open the file a third time on a third connection, asking for an exclusive oplock with create disposition OVERWRITE_IF. To my understanding this should trigger a break to none. In frame 66 I reply to the break response in frame 60, breaking to what was asked in frame 60: Level2. Frame 67 is what I find surprising and what I can not find in the documentation: I get a STATUS_REQUEST_NOT_ACCEPTED. According to [MS-SMB2], this only is sent in response to a lease break, not an oplock break. Although there was a REQUEST_NOT_ACCEPTED, the immediate reply to the pending opens shows me that some processing of the break response must have happened, I just don't find in [MS-SMB2] what exactly happened. Can you explain the sequence that happens in response to Frame 66? How does STATUS_REQUEST_NOT_ACCEPTED happen and how does the server do its further processing? In particular, what oplock level does the handle that got the oplock break have after this sequence. I can easily reproduce and slightly modify the test. If for example in frame 66 I break to "no oplock", I get a NT_STATUS_OK in frame 67. But the client that got the break can't know that frame 63 happened.
