On some of my Client 4.91 SP1 and 4.91 SP2 machines I'm getting an error
1497 when trying to unlock a workstation. I'm going to try to attach a
jpg of the error. In case it doesn't go through, the text of the error
message reads:
An unexpected error occurred while attempting to unlock the workstation.

Try to unlock the workstation again, or select a different credential
type for unlock.

Error - 1497 (0xFFFFFA27)

When I select windows as the unlock method it works fine, but the
default is to do eDir, and my users are complaining. I have some 4.90
machines that are working fine.
