User getting Random Access Denied Errors on SMB folders he is explicitly granted access too
Hi I have a user who repeatedly is getting access denied errors on a specific set of mapped folder shares, through either GPO or Script (tried both ways).
With out fail it's the same folders. Sometimes it doesn't happen for weeks and it only seems to happen to him no one else, everyone else who has permissions is fine. I thought it was profile issues but its across the board on multiple computers, first it started on a windows 7 computer, but then it spread to his VDIs and terminal servers which are Windows 10 and 2008/2012, but if you're in multiple instances it won't be on every one. The windows 7 machine will have it but the windows 10 machine won't, then vice versa, or the 2012 and 2008 will be fine but the windows 7 and 10 won't or all will be fine and working then in the middle of doing things in it, it stops working. So I though ACLs were corrupt. I removed all permissions and re-added them. Is there anything that could test to see what's going on? tried completely fresh installs and it continues. Created new profiles, tried local, tried roaming.
I don't see anything in the event viewer and like I said it only seems to be happening to this one user. who happens to need access to these files all the time.
There are no Denies on him or anyone and He's both explicitly allowed by user and Group.
I'm at a loss any help would be greatly appreciated.

We never have to unlock his account, nothing on his computer uses his user account to log into an application or service, everything is using windows passthrough credentials and they all seem perfectly fine. His phone is the only other thing that connects and that appears to be fine as well.

I think we found the problem, now we just need to find the culprit. Something is trying to pass through credentials that aren't the users to those specific drives. I found it logging in as a completely different user when he tried to connect and then stored credentials would show up in the windows credential store. if we delete them they're fine for a while and then they're back. funny thing is that the credentials aren't always there then randomly show up.
I feel it's an application that is doing it. It's trying to add a shared user that used to have access to the folders but since we updated our security processes that user was removed from access to those folders and granted to groups instead

The culprit was the saved credentials that kept getting passed around to the different profiles, since we deleted all the credentials on all the machines he logs into it seems to have stopped.
