None of our clients have been able to connect since applying the SP, so we're going to have to return to roll back, what we've found is that it wont let us turn off Network level authentication, if anyone can suggest a way to work around this then I would be very appreciative. We no longer have a support contract and I couldnt say what firmware they are on, but they did work with R2 previously with security set to negotiate on the server.
