Microsoft admitted Tuesday it made a technical error after it commandeered part of an Internet service's network in order to shut down a botnet, but the Nevada-based company says its services are still down. A federal court in Reno granted Microsoft an ex-parte restraining order that allowed it to take control of 22 domains run by No-IP, a DNS (Domain Name Service) provider owned by Vitalwerks, which was served the order on Monday.
