Windows users are getting Invalid Handle errors after update Managing Editor by Madalina Dinita Download PDF

Many Windows users are getting ‘The Handle is Invalid’ errors when they try to connect to Windows servers. It seems that this error code is affecting mainly Windows 7 users.

Today after installation of KB4480970 (automatically by Windows Update as Important) to our Windows 2008 R2 Standard Server the server stopped serve Clients by shared storage (haven’t tried anything else). The Client has issued an error Invalid handle and couldn’t connect (tried on Windows 7 Pro SP1 clients with installed KB4480970 only). After uninstallation it started work again, so the problem is positively in the KB4480970. Pls stop distribute the KB4480970 to the Windows 2008 R2 Server and correct the behavior.

However, some Windows 10 users have complained about this problem as well.

Everything was just fine – until this morning. All workstations throwing an error trying to access shared drives on a 2008 server – The handle is invalid. Pings out via IP and hostname. Can’t browse to it.
