Somebody asked me to look at an SBS 2003 server, it's asking for activation and after pressing the button to activate it does not allow me to login, it seems to be unlicensed software. I want the person to buy a valid license and be able to use the existing installation and just 'add' the valid license. What is the best procedure to handle this in a quick and painless way with minimal disruption to his network as this is his only windows domaincontroller. Your help is highly appreciated, thanks in advance! techtravel
