Windows Server 2003 - applied WCRY patch - restarted then RDP Failed (the workstation driver is not installed)

We had to uninstall and re-install the Client for Microsoft Networks to solve the issue.

Found the solution here: https://www.pntbrother.com/fix-the-workstation-driver-is-not-installed-windows-server-2003-active-directory/

"Go to “Control Panel“, and click “Network Connections“. Right-click your current network adapter, and click “Properties“. (Could be a wireless or a wired interface) Find and uninstall “Client for Microsoft Networks“. After uninstalling the item, click “Install” and choose “Client for Microsoft Networks” to install again (When you install Client for Microsoft Networks, it is located under Client category). If Windows asks you to restart, restart your Windows Server 2003."
