Recent Microsoft updates to Windows environments (Patch KB4480960 and KB4480970) have caused some people to experience connectivity issues when trying to access network shares.

 

.handle-invalid

The specific error message will amount to something referencing ‘Invalid Handle’ or ‘The Handle is Invalid’ when trying to access network shares (via UNC \\IP or \\name) or existing mapped network drives.

This is a frustrating error, however it is easy to fix

The fix is quite simple:

1) Start > Search > CMD > Right click > Run as Administrator.

2) On the black command prompt paste the following line where the cursor is flashing:

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

3) reboot your PC

Do this on all PCs that throw up ‘Invalid Handle’ related errors and after a restart you should be able to access the network shares.
