Android syncing with Win 7 LAN workstation

Posted on 2014-03-27

How can an Android device suddenly begin synchronizing itself with a My Pictures folder (not shared) on a LAN workstation?   And not just with one, but two different workstations!  Some facts:
-the company has a wireless router on its 50 node wired LAN.
-the wifi network is passworded and hidden.
-the 2 desktops involved (so far) are Win 7 boxes; they are not equipped with wifi adapters.
-the Android involved (ver. 4.1.2) is one of many personal devices connected to the LAN.  Others are not doing this.

Does the sync seem "live"?  What I mean by that is if you take a photo, does it show up automatically?

Does the user plug their phone into the computer to charge it?  Someone may have done this before and selected "sync photos" as one of the options of "what to do" when that class of device is detected.   Anytime you plug in the phone it will sync again automatically because that's what Windows was told to do.

Does the user have Dropbox?  Dropbox has a feature where it auto-uploads photos to the Dropbox and syncs to all connected devices automatically.  This can be disabled if that's the case.

Yes, the sync with Workstation A is (was) live.  (it’s syncing with two computers remember).   Workstation B was not tested for live sync, but since photos from B appeared on the Android even after usb connection from Computer C (for battery charge only) had been broken for a couple hours, it would seem live there too.  Android had been plugged in to Computer C to recharge battery.  Sync option was not chosen.  
I can’t find how to tell Win7 to sync or to not sync a folder.   Control Panel, Sync, isn’t very informative.  
The Picture folders on both A and B are marked “share with nobody”.  
Workstation A has Dropbox installed.  Workstations B and C do not.   Android user is not a Dropbox user.
Thanks for the help.

Interesting.  Have you had a look at the AutoPlay settings in Windows?

Control Panel\Hardware and Sound\AutoPlay

I think I would take a look at the ones for "Removable Drive" and see if there is a setting that could be checked for it.  This could be where the import is happening.  

The pictures folders may not be shared but they may be remote controlled using a GPO for Folder Redirection to the user's folder on a server.  Is it the same user logging in by chance?

In my head this is occuring:

User connected phone to Dropbox and even though the user isn't a dropbox user since it's installed it's device connection hook picked up that a device that has photos on it is present and the user could have clicked the option to import them.  Dropbox is installed by default on many Android phones (Samsung and Motorolla devices come to mind) and the user might have Dropbox in use there and not even remember setting it up.  One of our marketing people did this when she got a new phone, set the whole thing up on her phone and then linked her work computer to it.  She was letting someone from the office who hadn't had an account issued yet login as her and the girl could see her pictures since we use folder redirection.  It's a possibility that could be affecting you.

Found the cause.  (This time anyway.)  Win7 Media Streaming.   (Control panel, Network and sharing center) Turned off/on, syncing stops/starts.   And it's coming by wifi.  In/out of range breaks sync connection.   Must also involve a setting on this Android phone because other Android users in the building haven't mentioned anything.  More to learn........

Thanks for the info on Dropbox.    You can add LG to your list of Android phones that come with Dropbox installed!
