WIndows 11 Mapped Network Drive Changes The Target Folder "Randomly"

Hi

I have an odd drive mapping issue (and apparently random though I suspect its down to a cause and set of circumstances I havent figured out yet)

I have a NAS.

I have mapped a root folder on that NAS to be my Z drive (e.g Z:\Level 1)

Works perfectly.

However sometimes when I start/bring back the laptop from a sleep/restart after updates/some other action as yet unidentified, whilst the Z drive still exists in Windows Explorer, it is not the folder I originally mapped - it points to a sub folder down the tree from the root. e.g. Z:\Level1\Level2\Level3

I seem to recall a long time ago I had mapped the level 3 subfolder specifically as the Z drive in its own right (i.e. the network path was \nas\Level 1\Level 2\Level 3), then disconnected it, and then remapped the root folder level 1 as the Z drive. But sometimes my laptop seems to "remember" that Z: used to be mapped to Level 3 and reconnects to it (Level 3 still exists)

The only way that consistently works for me to re-map it is to go into safe mode, disconnect the wrong Z drive folder, re-map the folder I want to be on my Z drive and then reboot as normal.

Trying to disconnect the wrong Z drive folder with WIndows 11 not in safe mode generally doesnt work for me. Nor does disconnecting and rebooting, or disconnecting and restarting windows explorer. Windows explorer still shows the Z drive (wrong folder) but sometimes with a red X, and you can sometimes still browse to it and it works, other times it says it doesn't exist (even though it does)

I think that maybe an app somewhere must be trying to reconnect the wrong folder but for the life of me I cant see what it is, I have tried various permutations of elevated NET USE commands, messed around in the registry with mountpoints2.

ANy help/further things to research gratefully received. Whilst the workaround to fix it works, its a pain. Id rather have a stable mapping whenever whatever is causing this happens.

THanks
