  • For OWA you have to open port no 80 for HTTP and 443 for HTTPS.

    For Remote Web Workplace you have to open port no 4125 from internet to SBS server and port 3389 from SBS server to client machine.

  • Ok, thanks for the help.

    here is my problem.  I can use the OWA and the Remote Web Access.

    I can connect to both but when I try to connect to a computer on the network, I get the following error

    There is a problem with this website's security certificate.

    I have installed the certificate on the computer I am trying to connect with and it is in my trust certificates.

    I click on continue anyway and I am able to log on but I can not access a computer.  I can access on the Shared drives.

    Any suggestions?
