    Hello,

    Thanks for the responses.

    I eventually worked out what the issue was.

    Both of the computers have been imaged (but not using sysprep).
    Apparently with W11 RDP uses the computer SID, this is a change from W10.
    So the resolution in my case was to use SIDCHG to change the SID.

    Thanks again.

May be obvious, but worth checking that your W11 'client' has all the relevant services running (should be three of them listed in Services manager - ensure all are running.) Also check the Firewall is allowing it through.
