NASes Folders Locked

My home PCs and LAN !

3 NAS disappeared after PCs on the LAN had an unknown problem.

Buffalo NASes are finally visible and able to get drive letter assigned.
Took booting PCs AGAIN and restarting the NASes AGAIN !

But all folders of all NASes have a padlock symbol on the folders.
i.e. READ ONLY

Why? This was NOT how it ever was before.

I tried to change from read only but I am told I do not have permission !!!

What ? It is my PC and my NAS and my LAN. How dare MS keep me from
using my equipment !!! MANY Expletives deleted.

What to do ???

Now, this is a weird one.

"My question is why does the lock get assigned?

This happened to me when I moved all files from the
Synology NAS to a USB drive I attached directly to the NAS."

Maybe you're logged in on a temporary profile, and
you're no longer "Win7User" ? Perhaps the NAS login command
is stored to allow easy connection (mapping at startup), and then
once the connection is made, and the fact you're on a
temporary profile, you're denied access ? It was the fact
you had "stored credentials" that got you as far as you did.

Try "whoami" in a regular command prompt window (cmd.exe).
Not an administrator one. See who you really are.

You know it's a permission problem. Your job is to figure
out where the mis-match exists.

Yes, sometimes remote storage devices have their
security identifiers scrambled. It could happen,
but is pretty unlikely. The NAS would be as likely
to crash, if it was that unstable.
