we're trying to implement NTLM blocking (yes, this article is from 2009) and have enabled the relevant GPOs both on DCs and all member systems.

surprisingly enough most things work just fine, which is good. but joining new computers to the domain doesn't.

we receive "The request is not supported"

Any guidance on how to make this work?

    Hello there,

    If the issue happens for multiple PCs when joining the domain , it is suggested to check the status of the DCs and the replication among DCs, DNS configuration.
    Run command the DCs and confirm if there are any errors:
    Dcdiag /v >c:\dcdiag1.log
    Repadmin /syncall /APeD
    Repadmin /showrepl >C:\repl.txt
    Repadmin /showreps *
    Ipconfig /all > C:\dc.txt

    Hope this resolves your Query !!
