Windows 7 and Release 19.222.1110.0006

[BRYAN BURNETT]

After having OD, release 19.222.1110.0006, deployed in our environment, we cannot authenticate with the OD client. OD is available via the web and other desktop clients, such as Outlook, continue to work. After authentication fails, the error message returned is 0x8004de40. We have opened a ticket. Is any else experiencing this outage?
