Phantom network drive connections (that do themselves)

Luc BATICLE 1 Reputation point


I have a very curious problem on my Windows 11 installation. Some "phantom" drives are mounting themselves. It's in time, I don't know what the reason is.

When my PC starts up, everything is fine, and then as time goes by, a volume from my NAS server mounts itself on all available letters. It seems that it goes down, starting from the last available one, then the previous one and so on to occupy after a while all the letters with my "home" directory of my synology, normally mounted only in "H:".

When I unmount everything, it starts again...

I am in Windows 11 21H2 professional version, in a workgroup context, and I have not installed any login script or anything else.

Can you help me to investigate this behavior?

    Method 1:

    Open command prompt as administrator and type below commands


    list volume (here is now seen which volume has letter)

    select volume x (x is a volume number when you want remove)

    remove letter=x (x is a selected volume letters)

    Method 2

    Open a Command Prompt (with Admin)

    subst x: /d ( where X: is the drive letter of the phantom drive. )

    Also, Please check if there is any GPO which is configured to mount shared folders for the users.
