A Windows 7 client sends us write requests that we think are invalid because the request size is longer than 64k and they did not negotiate the "large writes" capability when they started talking to us. Just deal with it...

Internal reviewer: Kevin Crowe

Verified this client+application can write to our server.
Field tested for quite some time.

  2. is this the kind of situation where we should consider logging a "Your client is misbehaving message" once per-client, or is this something Windows gets wrong always? If it's not misconfiguration or whatever, don't worry about it.

    1. It's not worth writing warnings about. It's one of those (many) areas where the spec. is open to interpretation.
      We could annoy the admin with messages, but that will not make MS fix this client.

  3. Would stating the version more precisely help?
    (is it 7 only, 7 and above, specific revs of 7?)

    1. It happened in one of the updates. Sorry, I'm not sure exactly which one.
