Anyway! I could not get to our SAN - or very many network computers - after I finished my update.
The Solution - which I could not find and hopefully you have - is setting a registry value and adding a DWord value. As below:
Windows Registry Editor Version 5.00Edit the Other Domains value to be 7
Add "RequireSecureNegotiate" and it should default to 0 (zero).
That fixes it all.
While we are on the subject of Windows 8 - some have complained that they can't run File Explorer as an admin. Here is the fix for that :
Create new shortcut on the desktop... right click in an open area and select "new" and select "shortcut."
For the location, type "explorer.exe" and click "Next."
Type a name in - like "File Explorer (Admin)" and click "Finish."
Right click on the new shortcut and select "properties." Click "Advanced."
Put a check mark in "run as administrator" and click "OK" until you are back at the desktop.
Presto! You can now browse as an admin!
