Hi,

I have 3 computers at my disposal at work, 2 of them connected to a WiFi network intended for visitors -> no restrictions -> everything's fine. But the third one is a desktop connected to intranet and has internet access as well but with certain restrictions. I've installed the BOINC manager and virtual box and it works but when I try to add a project it says connection failed, tried several times and still the same. My best guess is that a specific port used by the client is being blocked. Any way how to circumvent this? any other ideas?

Thanks

BOINC.exe needs TCP port 80 and 443 open in the firewall for internet connections.
But VirtualBox installs a virtual network connection of its own. This may need a reboot of the computer to work. If you haven't tried that yet, try that first.
Also, VirtualBox is only really needed if you plan on running any of the projects (http://boinc.berkeley.edu/wiki/VirtualBox#BOINC_projects_with_VM_apps) that use VirtualBox. If you do not, it's not needed and you can uninstall VirtualBox, then in the future just upgrade BOINC using the installer without VirtualBox.
