can't login using [email protected] while offline

[Guest]

a handfull of our users are unable to login to their windowsXp pro systems
using their (e-mail address removed) username while offline. They receive a domain
unavailable error. However, they are able to login using their username less
the @domain.com and then manually select their domain from the location drop
down. They are able to use the @pharmion.com username while online. This is
in a windows2000/XP AD environment.

Can anyone help me understand this behavior? Thank you!

When they manually select from the drop down, what are they selecting? Maybe
the local computer name?

When you type in username@domain, you're overriding the domain name that may be
contained in the drop down (or defaulted if no drop down selection made). If
login defaults to the local computer, and you typed in username@domain, you'd
authenticate to the domain. If you just typed in username, OTOH, you'd
authenticate to the local computer.

They choose the AD domain and not the local machine when they select their
domain which is what they need to do. Any other thoughts would be greatly
appreciated. Thank you.

If you login once to the domain, when the computer is online, your SID and
password will be cached on the computer. If you are offline later, and domain
policy permits authentication against cached credentials, you could login using
a cached account / password.

I'm not sure of the relevance of using the username@domain form, as opposed to
username and explicitly selecting the domain in the drop down. Neither choice
overrides the absence of cached credentials when the computer is offline. If
the computer is going to be offline, you will have to have domain credentials
cached, ie you have to have initially logged on when the computer is connected
to the domain.

Hi Chuck,

I appreciate your responses. In all cases our domain policies allow the use
of domain cahced credentials. Our situation is specific to using the
@domain.com form of the username offline after domain credentials have been
cached (by logging in using @domain.com form while on the network and
connected to AD). Also, in the cases when the @domain.com form does not work
while offline, the short username form +specified domain does work. It's as
if the cached credentials only recognize the short username form even though
the credentials were created using the @domain.com form.

Thank you.
