TicketDesk is an issue tracking system for IT Help Desks.
TicketDesk is efficient and designed to do only one thing, facilitate communications between help desk staff and end users. The overriding design goal is to be as simple and frictionless for both users and help desk staff as is possible.
TicketDesk 2 is an ASP.NET MVC web application written in C# targeting the .NET 4.5 framework. It includes a simple database with support for SQL Server 2005, 2008, or 2012 (including express and localdb editions). It can leverage SQL server for membership and role based security or integrate with windows authentication and Active Directory groups.
