PSA: recent Windows updates disabling SMB1

Windows April/May updates are disabling SMB1 protocol on computers / servers.

This can cause various communication issues between workstations and servers. Examples are credit card readers communicating with host software and browsing file shares via VPN.

This is detectable during a packet capture, there will be a reset packet immediately after a protocol negotiation.

Please see link for PowerShell commands for checking, enabling, and disabling various SMB versions.
