Updates released this week from Microsoft are keeping Windows users from connecting to servers that they can normally connect to. If you suddenly can't make a Remote Desktop (RDP) connection, go to Winsoft (\\software\winsoft; a.k.a. the "K:" drive) and double click on Fix_RDP. You should immediately be able to make your regular RDP connections; no reboot necessary.

The relevant Windows Updates are:

KB4103725 (Windows 8/10)
KB4103727 (Server 2016/2012)
KB4103718 (Windows 7)

Do NOT try to remove these updates directly. Use the patch on the K: drive instead.

If you continue to have problems connecting, contact AskIT.
