Server 2003 product activation problem

[signtech]

I wonder if somebody could shed some light to a particular product activation problem that I’m having with SERVER 2003 Enterprise edition.

We were having some electrical power outages that knocked off line our server and we had our SERVER 2003 software activated, for some reason when I try to log in to the OS it tell me that the product needs activation. Once I enter the product activation screen it tell that the product is already activated and it sends me back to the log in window repeating the same cycle.

I would appreciate if somebody has a solution on how I could get past the login screen, all the server services seem to be online. One thing is that this server is not connected to the Internet or modem.
