Lotus Notes 4.5

Over the weekend my Lotus Notes server crashed. Bad hard disk of course, but I had a back up from the previous Friday. I was able to restore everithing on the dead hard drive to the new one but when I restarted notes services in Windows NT the LotusNotes server asked me to enter the password for the server.id which I don’t know. Is there a way to reset the password?

Thanks for all the help I can get.
