KB4480970 - Windows Server 2008 and Windows 7 Bug

Posted Thursday 10th January 2019 16:34

It’s early days, however, the latest update for Windows Server 2008 and Windows 7 seems to be causing a growing number of user’s issues related to workstations and servers blocking RDP and Network Shares.

The update ID containing this bug is KB4480970 and displays the error "The handle is invalid" when trying to access PC’s with this bug and "The local security authority cannot be contacted. This might be due to an expired password.” when trying to connect via Remote Desktop.

We recommend not updating currently, although if you already have; rolling back the update seems to fix the issue. If you’re still experiencing issues, please get in touch with Ahead4 by email on info@ahead4.com or phone us on 01245 426 163.
