I tried that but it didn't solve the problem. However it changed the error pattern. Now on Windows
2021R2 Server accessing the share results in a network error message (this server should have both
SMB1 and SMB2 enabled). Windows 2019 Server keeps on asking for user/password accompanied by an
"access denied" message (this server has SMB1 disabled).

Yes, as mentioned it used to work fine for me as well prior to installing the security updates.
