Along with Microsoft Visio 2002 Professional, Microsoft introduced Visio Enterprise Network Tools and Visio Network Center. Visio Enterprise Network Tools was an add-on product that enabled automated network and directory services diagramming. Visio Network Center was a subscription-based website where users could locate the latest network documentation content and exact-replica network equipment shapes from 500 leading manufacturers.[16] Visio Enterprise Network Tools was discontinued in July 2002.[17] The following year, Microsoft released a patch which gave Enterprise Network Tools users access to the network equipment shapes via Visio's built-in Find Shape feature.[18] Visio 2007 was released on November 30, 2006.
