Microsoft TechNet is a Microsoft program and resource for technical information, news, and events for IT professionals. Along with a website, they also produce a monthly subscription magazine titled "TechNet Magazine".

TechNet was originally available only to customers with paid subscriptions; however, it has been expanded to include public information, webcasts, local events, and free newsletters. They have also started an open source blog on April 6, 2006 called Port 25 to publicly explore that business model and provide discussion forums.

As of July 18, 2006, the Sysinternals tools were merged into TechNet.

TechNet's primary web presence at technet.microsoft.com is a collection of sites for the IT professional community that provide information, documentation, and discussion which is authored both by Microsoft and by the community at large. Recent emphasis on and incorporation of applications such as forums, blogs, library annotations, and social bookmarking is changing the nature of the TechNet site from a one-way information service to an open dialog between Microsoft and the IT professional community. The main website, and most of its constituent applications below are available in 12 or more languages.
