Why is Dyn Updater all of a sudden spawning 20+ UAC prompts on my computer?

User_LB663 Member Posts: 8 Green Ribbon

I use Dyn Updater to update my dynamic IP. Has worked without issues. Now today for some unexplained reason, a bunch of UAC prompts were spawned by Dyn Updater regarding making some sort of change on my system.

I had to manually close some 20 of them. Then a few hours later it happened again.

The patch notes for this application say as of 2010 it was updated to allow non-admin users to perform some activities with the use of UAC prompts, but I'm an administrator on my machine and I've been using this for years since 2010 so I don't understand why this is occurring.

Anyone have any ideas?

    Only 20? I got 91. Also looking for a solution. My guess is the demon is hanging or stops responding and it keeps trying to restart it. I assume that it can't reach the update server. But that's just a guess. Would like to know why this suddenly started.

    So do I. When restarted, DYNupdater does not connect to the server.There seems to be a problem connecting or logging in.

    I'm having the same issue, can anyone from Oracle give us a solution/workaround or at lease a root cause of why is this happening suddenly?

    I, as well as a number of clients which I've setup Dyn DNS have the same issues starting at 15:47 yesterday afternoon (Jul 19, 2021) according to the daemon and frontend logs.

    Try clicking "Remove Account" from the Dyn Updater.

    Select the account "none".

    In my case, my current account appear back again and the Host Active turned green.

    Hope this helps someone.

    For what it's worth, my host already reports green. Was yours prior to removing/readding?

    Also 20+ was being humble. It does spawn a hell of a lot more than that like the above stated LOL.

    Seems it is indeed crashing at some point (only a couple of these events in my event viewer), but the Dyn logs show a buttload of the following events:

    2021-07-20 07:26:10,496 - frontend - WARNING - Failed to receive API response from backend. Attempting to restart daemon.

    2021-07-20 07:26:10,841 - daemon - INFO - Insufficient privileges, relaunching as admin.

    I also have the following event, which suggests it's trying to run a number of python scripts, including updating the NIC, but I have this setting disabled as I do not wish to have my NIC set to use DynDNS servers. Not sure if it's related or not.

    Happening to me as well, no need to repeat the details others already have. This is infuriating and we need it to stop pronto!

    I've submitted an email to support. Will see what they say. I suggest everyone else do the same.

    So far this is what's being said. I do not understand the direction as the service is already running as local SYSTEM so it should already be running with the highest level privileges possible.

    I would highly suggest NOT disabling UAC entirely.

    Good afternoon Matthew,

    In looking into this problem, this elevation means that this application needs to be run as the administrator.

    Also, you can navigate to C:\program files (x86)\Dyn\updater

    and find dyn_updater.exe

    right-click on it and select properties

    Select the Compatibility tab

    select the box Run this program as an administrator

    select apply

    then ok.

    If this does not work, you can disable UAC until the bug has been fixed:

    UAC off

    To turn off UAC:

    Type UAC into the Windows Start menu.

    Click "Change User Account Control settings."

    Move the slider down to "Never Notify."

    Click OK and then restart the computer.

    Thank you for your patience.

    I'm fighting the same thing, I thought maybe it was a change with the July cumulative update, but uninstalling it presented no relief. I'd already tried setting the .exe to run as admin, but that appears to actually not launch it at all, oh, and running the front-end as admin prevents access to the configuration data as that's apparently only available when running in normal user contest. I'm curious to see what response I get when support replies to the ticket I opened today as well.
