"Username or Password is incorrect" when trying to use a shared printer

I believe I have the problem described in KB 5070568 with several MSI Cubi computers running Windows 11. After months of use they have suddenly become unable to connect to a shared printer on one of the Cubi's. ALL the Cubi's, however, have the same problem but Win 10 computers on the network have no problem. Nothing has changed except, of course, Windows updates. I get the same error message when trying to map a network drive, but all the computers can be pinged and otherwise work on the network fine. There is supposedly a Group Policy mod that can be used to get around this, but I can't find it. Does anyone have that mod OR any suggestions?

Thanks.

    The issue is essentially that newer versions of Windows (Windows 11, in your case) are stricter about SMB version negotiation and may fail to connect to SMBv1 or SMBv2 shares, which are older protocols. This can cause issues with printer shares and network drive mappings.
