The logon credentials supplied were incorrect

[Scott Christopher]

OK... here's a bit of a description of the hardware / software I'm
dealing with...

- Active Directory resides on a Microsoft Windows Server 2003
Standard Edition
- Microsoft Exchange 2007 resides on Microsoft Windows Server 2003
Standard Edition

I'm not real strong with networking, so please bear with me, as I try
to explain my situation.

We have users running Outlook 2007, 2003, 2000. Everyone is receiving
their e-mails through Microsoft Exchange Server, not via POP3.
Everything has been working fine.

Yesterday we had a power outage, and I was unable to shut the servers
down before the UPS's depleted.

Now every user that is using Outlook 2000 is unable to get to their e-
mail. When they start Outlook 2000 and they type their Username,
Domain, and Password, they get the message, "The logon credentials
supplied were incorrect. Make sure your username and domain are
correct, then type your password again."

I have checked their accounts, and they are also able to log on to
Outlook Web Access.

Does anyone know what the issue might be? I don't think i can get
approval for upgrades right now, and the supervisors don't want the
users to have to use Outlook web access.

Thank you for any help you can give me.

At a guess, user logon credentials are in cached mode, users have no
*actuall* access to the server, and so exchange.

Check your LAN switch - perhaps it got #!#@$ in the power outtage, and
just needs a power-cycle to fix it all.

PS: why isn't your UPS set to gracefully shutdown the server?
