    Hi Guys,

    I installed VB and PHPVB 4.2 around six months ago and all was working fine. I have now gone to set up another VM and for some reason remote display is not working; I am receiving the above error.

    I have entered port 3389 and opened this up in the firewall:
    ACCEPT tcp -- anywhere anywhere tcp dpt:3389

    After running a few VBoxmanage commands, which didn't solve the issue: modifyvm "VM name" --vrde on and VBoxManage modifyvm "VM name" --vrdeport 3389 (I assume this is what PHPVB is doing anyway, when clicking remote display and putting the port in)

    I decided to try a catch all solution and upgrade VB and PHPVB. I've successfully upgraded but still have the same issue.

    Can anyone point me in the right direction with this?

    Thanks in advance, Rick.
