Here's a possible fix from KB232386:
To resolve this issue, log on to your computer locally using an account with administrative privileges and set the time and date to match the time and date on the domain controller that validates your logon. Below is list of steps that can be used to synchronize the time.
Click Start, Run
Type in CMD and click OK
At the command prompt type something similar to the following:NET TIME /DOMAIN:name /SET
Where "name" is the domain name being used by the computer. If you are not certain what the domain name should be replace name with "%userdomain%" without the quotes.
