HTC P3300 / HTC Touch Cruise and AUTD

Discussion in 'Windows Small Business Server' started by Richard Johansson, Parnasso, May 3, 2008.

  1. Hi!
    I have an issue with two different HTC devices that I have in my
    organisation. The basis of all communication is an SBS2003R2 with Exchange
    SP2. I have trouble with different clients' phones receiving the emails at
    different speed. The HTC P3300 was initially released with Windows Mobile 5
    but in March 2008, HTC released a Windows Mobile 6 update for the P3300. I
    loaded this image to my P3300 and it worked perfectly well with both
    DirectPush and all the other connections that I did set ut for it.

    The issue is my colleagues that all have changed their PDAs to HTC Touch
    Cruise instead. Both their phones any mine are using Windows Mobile 6 but
    with the difference that theirs are preinstalled with Win Mobile 6 from
    delivery. The problem that they are experiencing is that their DirectPush
    isn't very "Direct". Instead of having their emails and calendar updates
    delivered to their PDAs instantaneously, the delay might be up to a few
    hours. In my own PDA, the P3300, this issue is non-existing and hence I am
    not experiencing the problem.

    Okay, so I went looking for some KBs and found that this has to do with the
    firewall timeout settings. After having changed the timeout settings for the
    firewall, the connection for my PDA got even better than before, but the
    issue persisted on their PDAs.

    Is there anyone having any experience with this kind of problem? I am using
    a mixture of Certificate and non-Certificate-connections from the four PDAs
    (one P3300 and three Touch Cruise).

    Firstly, you should be using SSL on all of them - if you don't have a
    trusted third party cert then you'll need to copy the exported self-signed
    cert to each device & install it. See whether that makes any difference.
    HTTPS is all you should need open for this - no HTTP (block that in your
    firewall if it's open).

    This can't be a firewall issue if the problem is not consistent across

  3. Okay, so I reckon that this should not be a firewall issue if the problem is
    not consistent across the organisation, but I still am not very much wiser
    about the issues that this causes. Does it make any difference that the P3300
    is older than the Touch Cruise or is that inconvenient in this sence?

    You are telling me to close the port 80 on my firewall - won't I need it for
    RWW and OWA?

  5. Okay, so then I know. I will turn that port off quite soon then. Thank you
    in advance.

  6. No, I have not tried this, but will do.
