    Description

    I log into the virtual office, I click on the bookmark, it seems to go through and then I got the following error:

    "Because of a protocol error detected at the client (code 0x1104), this session will be disconnected"

    Resolution

    On the remote PC side.

    • Ensure that your remote PC is ready to accept remote connections.
    •  Windows firewall might be blocking the remote connections.
    •  Antivirus software might be blocking the remote connections.


    On the firewall side.

    • Please ensure that you have your firewall in the latest general release at least.
    •  Ensure as well that the firewall is able to reach the remote server (Navigate to system|diagnostics and try to ping the server).
    • Check the VPN access list of the user that logs to the Virtual Office, he must have the network of the server that it’s trying to reach.
    • Configure as well the client routes and IP for the Net Extender client are configured even though you are going to use the Virtual Office.


    How to Test:

    After applying all the changes try to log into the bookmark again.
