  1. After I did this, Windows would boot up, it went into Recovery blue screen, now I may have to reimage the computer.

  2. I wasn’t able to see any devices or files on my network until I enabled SMB 1. However, in the same article that told me how to enable that, I was warned that SMB 1 is “VERY UNSAFE” and should not be selected. But if I uncheck that box, then I can’t print to my usb printers connected to my desktop. It is very frustrating. Darned if I do it, and darned if I don’t. Is there any other way to have my network see my devices and files without running SMB 1client and server? Thank you.

  3. It worked for me, thanks.
    @Dario: When you have a proprietary industrial system that has Win2003 SRV underneath you have to enable everything to make it work as it used to …

  4. “Your problem should be solved.”

    ….and then you’ll be having new ones.
    What about SMBv1 is deprecated because it’s unsecure and easily brakeable… basically your client will have more vulnerabilities once SMBv1 is enabled.
    Just do it if it is worthy should be the adv here!

  5. Even after doing this, I still had to access the Windows 2003 Server shares by its IP address. Using the server name did not work even though I was able to ping it using the server name.
