username\domain vs [email protected]

    In the last couple of weeks, services on some of my Windows 2003 servers
    have been failing.
    If I change username\domain to [email protected], they start and stay running.

    Is anyone aware of articles discussing the difference between using
    username\domain and [email protected]?

    Is it [email protected] or or , etc? You posted a
    single label name, which is highly problematic with an AD domain and must be
    fixed or expect numerous other problems.

    As for the differences, the domain\username (you posted it backwards and may
    be the whole issue) is the legacy NetBIOS method, whereas the
    is what we call the UPN (Universal Principal Name), which is
    purely DNS based. An application must support this method (such as AD aware
    apps, and others), otherwise, you will have to revert to the legacy method.

    So the UPN would be

    Thank you for correcting me. Yes, I am using domain\username
    Now that I understand this to be NetBIOS name, it seems there is some
    NetBIOS flakiness in my network.

    Do you know if NetBIOSname\username require a WINS server in the environment?

    Depends on your infrastructure. In a multi-subnetted environment, yes. In a
    single subnet, no, not really. It will use broadcast.

    Can you define "flakiness?"

    Flakiness - Services, including SQL Server and Windows SharePoint Services
    Search, Timer, etc are not consistently starting when a server is rebooted.
    These services are set to log on as domain accounts. Sometimes they do
    start, but most of the time they do not. Services set to Log On As Local and
    Network Service start fine.

    When I manually try to start the service, I put in the same password as I
    did yesterday and the service starts. It is as if the server is not
    remembering service log on passwords.

    I was hoping that this behavior was constrained to NetBIOSname\username, but
    now I've demostrated that this is also happening to services with log on
    accounts set up as .

    One path I am lookin down is researching the order things start on the
    server. I'd like to find out if these services are trying to start before
    the server has established connectivity to a domain controller.

    It looks like this is a Group Policy - Local Security Setting - Local Policy
    - User Rights Assignment - Log on as a service issue.

    I am going to add these accounts overnight and post my results!

    Was something in the GPOs changed regarding this setting or any other
    setting? Restrict Anonymous changed? Is this a DC?
