right!īefore you start it is always a good idea to check that all your servers in your environment support SMB 2.0 or later.

While we still don’t have flying cars, at least we can get rid of SMB 1…. If you want any more convincing we are now 30 years in the future from the release of the original SMB 1 protocol (and the Back to the Future movie). Not that I should have to explain, but in case you need a refresher it is old (30 years old) it is slow (especially over high-latency links) and its was superseded over a decade ago with the release of Windows Vista, that’s right… VISTA!!!! So, by now you should be convinced that SMB 1 is really bad and that you need to banish the protocol from your network. In case you have not got the message yet SMB 1 protocol Bad and that according to Microsoft you should “Stop using SMB1”.
