Why "DOMAIN.LOCAL\Administrator"? [message #155766] Thu, 04 June 2009 11:08 Go to next message

Recently I installed a Windows 2008 server and joined it to our windows
2003-domain.

The problem is that I cannot login with just "administrator", I have to use
"DOMAIN.LOCAL\Administrator", i.e fqdn in caps plus the big A.

"DOMAIN\Administrator" does not work.
"DOMAIN.LOCAL\administrator" does not work.

Why is this??? I can't find ONE SINGLE POST on the internet that explains
this!

I'm surprised, too. Assuming the NetBIOS domain name is 'domain,' you should
be able to simply logon using domain\administrator. Usernames with Windows,
are not case sensitive.

Any errrors in the event logs?

Actually, the UPN (Universal Principle Name) would be user@domain.local.

You can't use the NetBIOS name of the domain in a UPN. So for the original
poster, Pazuzu, it would be administrator@domain.local.

Hello Pazuzu,

Never saw that before. As said from Ace it should work with the NetBios name.
You can also prevent the domain name before the user name with this GPO setting.

Configure following GPO setting:
Computer configuration, administrative templates, system, logon, in the right
pane choose "Assign a default domain for logon", here you can specify the
domain name, tested it with the netbios name and it works.


Best regards

Thanks for the answer.

Actually no combination of @ works. Not even "Administrator@DOMAIN.LOCAL".
I've tried all combinations: large and small letters, fqdn and netbios domain
name.

Could this be a hint??

I noticed that 'name service provider' in network properties (client for
microsoft network) is blank. I try to set it to "Windows locator" but it
doesn't stick. If I logoff and logon, the box is blank again. Could this have
something to do with it? I have not found out why it want to stay blank...
maybe it's normal in win2008srv and vista??

And it's the same login problem in vista yes.

The netbios name is DOMAIN and ipconfig says dns prefix is "domain.local".

The event log says:
An account failed to log on.

Subject:
Security ID: SYSTEM
Account Name: BELLINI$
Account Domain: LENTUS
Logon ID: 0x3e7

Logon Type: 10

Account For Which Logon Failed:
Security ID: NULL SID
Account Name: Administrator
Account Domain: LENTUS

Failure Information:
Failure Reason: Unknown user name or bad password.
Status: 0xc000006d
Sub Status: 0xc000006a

Are there any services disabled? Is NetBIOS disabled? How about the user's
AD account properties, is there a UPN configured? Are you using your ISP's
DNS or the router's IP as a DNS address in any machine's IP properties?
