    Bizarre Remote Desktop activity.


    I am running a Win 7 64 bit PC. It runs a little known, but very powerful email client called The Bat!

    I have run a (now) legacy version of The Bat1 for probably 15 years, accessing and using it remotely from another PC on the same home, hard wired, network. This other PC is also running Win 7 64 bit.

    Now, previously I left TB! running 24 hours a day, seven days a week. I could open and close the Remote Desktop sessions with impunity, TB! was always still running in exactly the same state as I had left it in, when I restarted a Remote Desktop connection, as were any other apps on the remote PC that I had left open.

    I updated TB! recently to the current version. The update seemed to go fine, and it SEEMED to perform very well. BUT, I soon discovered that whenever the Remote Desktop session was closed, either at the remote end, or at the PC running TB!, this now updated mail application took it upon itself to perform a mail folder check, and in doing so freeze up and lock solid, demanding that I use Task Manager to kill the folder check process, and the main mail application.itself

    Now, this may well be, and I assume IS some anomaly with this later version of TB!, but how and why could closing a Remote Desktop session from either the remote or local PC cause an application to "do things" of its own accord? I have never seen any other application act like this...

    Any insight greatly appreciated, my legacy version of TB! does not do this, and it never has, it was always there on the remote PC as left, and nor has any other app I have ever run on the remote PC.

    Bizarre, or can anyone suggest a reason? Thanks and all the best.

    Hi Basil,

    check the change log details for TB,, my guess it has todo with SMB1, which has become a depracted feature

    torchwood, thanks very much for the reply, but that's gone way over my head. I searched as far back as i could in The Bat! equivalent of changelogs for anything seemingly yo do with SMB, but couldn't find anything.

    Would you mind telling me in idiot proof terminology what SMB is and how it might be the cause o my Remote Desktop to The Bat! issues please?

    Hi Basil,

    for a quick overview of SMB1, have a read of this tutorial....

    Enable or Disable SMB1 File Sharing Protocol in Windows | Tutorials

    and The Wannacry malware used smb1 deficiencies

    Had a look at TB's securities features and the other problem could be TLS,.
    (both SMB1 and TLS are file sharing protocol features)

    ok, enough of the blabber
    on BOTH/ALL computers you are going to have to check the following settings in
    Control panel >>Programs/Feaures>>Features(top left)... then in the smaller window that opens
    ensure that TLS and SMB have the lowest versions both Checked
    note as you will see in the tutorial and likely in TB's security notes its not recommended

    Both the above protocol settings are likely also options in TB

    Thanks for your patience and the update with links, but neither computer has any mention of either SMB or TLS in that box. Both run Win 7 64 bit SP2.

    I would just use TightVNC and Zerotier. I bet you're lit up like a Christmas try at Shodan, Censys et al...

    NEVER forward VNC...

    Samba and RDP are CVE plagued nonsense in my opinion.
