Users cant connect to shared drives on win 7 pc

I have a client with three pcs all running win 7 pro. One pc is acting as a  "server" with multiple shares. This has been working for years.

This morning they came in and when they tried to login directly to the "server" they got a profile error and through them back to the main login screen. At this point the other pcs where able to access the shares without any issues, we just couldn't login directly with the primary (admin prived) account. Other local accounts were able to login. When a secondary account (not admin prived)  logged in I remoted in and every time we tried to run an elevated session (ie command prompt, manage pc) it came back with an invalid path. I ran malwarebytes and it came back clean.

After getting to safemode we were able to login to the primary account and I had them add a secondary account to the local admin group. rebooted. I then able  to remote in the the newly admin added account remotely. I fixed the profile isssue in the reg (deleteted temp prof and removed the .bak) and on the next boot the primary account was fully accessible.

The problem is now none of the other pcs can access the shares. The previous mapped drives come up handle invalid and clicking on the pc give be a network path not found. even tried using the ip address instead of netbois name. same thing happened.

after searching internet tried modifying secpol ntlm levels, didn't help
checked permissions looks good. turned sharing off and on same thing.

any ideas

issue appears to be with microsoft patch  KB4480970 which was automatically installed last night. After removing it, shares became accessible.

Looking around on the internet there may also be a reg fix (see below)  BUT I HAVE NOT TESTED IT!

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f

I just tested the reg fix on another pc with sharing issues and it did work. Again fix is:

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
