Can not join domain ADS again

[serwise]

Hi
I disconected from the domain and tried to join again, but it does not work!

I got the Error Message that User oder Password is incorrect, but the computer account was created on the ADS....

Does anyone has an idea?
Is the ADS integration realy working on that device???

Thanks
Martin

Thats the error Message after Reboot and try again:

Error : Incorrect administrator ID or password

[serwise]

Now i changed a flag from the admin User Account i use for the N4100:

Set the Do not require Kerberos pre-authentication flag on the user’s account. Alternatively, consider upgrading to the most recent MIT reference distribution of Kerberos authentication.

But get now a new Error Message:
Error : Administrator permission denied

Thanks for any help!
