Windows 10 unable to connect to 2000 server shared folders After update

It appears that after a recent update to Windows 10, work stations are suddenly unable to connect to shared folders on a Windows 2000 server (I know that support for these machines have expired, but some of them are still around). When trying to access the shared folder the user with get a "Windows Security" pop up requesting the user to "Enter network credentials". Requesting both a user name and password, but nothing works. I tried empty password issues, but none of those work. And I verified that the password had not been changed. I also tried connecting to the folder via IP address instead of the server name. It also didn't work. 

This is what worked:

  1. Start Registry Editor. To do this, click Start, click Run, type Regedit, and then press ENTER.
  2. Locate and then click following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA
  3. Locate the LmCompatibilityLevel registry value.



    If the registry value is not present, follow these steps to create it:
    1. Select the registry subkey that is listed in step 2.
    2. On the Edit menu, point to New, and then click DWORD Value.
    3. Type LmCompatibilityLevel, and then press ENTER.
  4. Set the DWORD value to 1. To do this, click Modify on the Edit menu, type 1 in the Value data box, and then click OK

The instructions suggested a reboot was necessary, but I found it was not. Access to the folders was available after saving this value. In all the PCs I did this in, LmCompatibilityLevel was missing.
