I've never had issues with cached credentials connecting to shares in the
past. Recently something has changed and I'm getting some weird messages.
This is the error i'm getting in event viewer when trying to connect to
shares.

The Security System detected an attempted downgrade attack for server
cifs/gss-dc3.  The failure code from authentication protocol Kerberos was
"There are currently no logon servers available to service the logon request.
(0xc000005e)".

The main problem is with the cached credentials when trying to connect to a
share it will error out with this error:

"Logon Unsuccessful: The user name you typed is the same as the user name
you logged in with. That user name has already been tried. A domain
controller cannot be found to verify that user name."

If I try to map the drive with another domain user it works fine so it does
have a connection with the DC. It is almost as if there is some kerberos
problem.
