Current time on server doesn't match the current network time and won't let Admin log in

I have an SBS 2003 server that downloaded and installed some automatic updates and then rebooted.  When it finally (about 20 min later) came to the logon screen it wouldn't accept my u/p because it said the current time on the server didn't match the current time on the network.  This computer is the PDC of the network and the only server on the network.  It is only connected to the internet via a dial-up modem (which was not dialed at the time).  

Can someone please help?

  Very odd indeed.
  If you've already tried disconnecting the network, next step would be to try the time in the bios.
  I believe the systems tolerate a one hour difference, so you could try adjusting by an hour.
  also do you recall changing your time zone recently?
Hi whdjr,

  I haven't come across this yet, but if you're in a pinch, I'd pull the network cable from the SBS box and try again

Thanks,  I already did that.  That's one reason it's so confusing, if there is no network how can the times be different.

Hi whdjr,

you can use the NET TIME command to synchronize your
workstation's clock with another workstation or server's clock. To do so,
open a command line or Run dialog box and enter the command

NET TIME \\ComputerName /SET /YES

Where ComputerName is the name of the workstation or server that you want
to synchronize with. If your workstation is a member of an NT domain, you
may want to synchronize your clock with your Primary Domain Controller. To
run this command every time you log on, put it in a batch file and add the
file to your Startup Menu.

How can I do any of this when it won't let me log in?  This is the administrator account on the PDC SBS server 2003.

Boot into Safe Mode and you will be able to log in.

Then, you need to make sure things are configured properly per this KB article:

Thanks for the help fruhj.  It was the time in the BIOS.  It was 12/2003.  I don't know how that happened.

Thanks again,
