IT Helpdesk Ticket System

You can try either MouseTracks http://www.gritware.com/ or TrackIT http://www.blueocean.com/

Also try this website http://www.customerservicepoint.com/help-desk-software.html it has some other programs that may be of interest.

Although it is used for bug tracking, Bugzilla might fit the bill. It is both Open Source and FREE.

Double Choco Latte

Double Choco Latte is a GNU Enterprise package that provides basic project management capabilities, time tracking on tasks, call tracking, email notifications, online documents, statistical reports, a report engine, and more features are either working or being developed/planned. It can be displayed inside of a phpGroupWare installation or be used stand-alone. It is licensed under the GPL (GNU Public License), which means it is free to study, distribute, modify, and use.

dcl.sourceforge.net

We've just recently started using Readydesk (Readydesk.com). Its inexpensive and seems to do just about everything we need including e-mail notifications and ticket submission. It uses MSSQL or Access and allows for almost unlimited custom fields for tracking your own information.
Another solution we evaluated and almost went with was ZenTrack. Its an Open Source Help Desk/Ticketing system based on mysql/PHP which seems to have a pretty active user community.

I have used Remedy, TOP, and Track-IT. I can't recommend any of those.

We're moving over to HP Open Desk and I've heard nothing but good things about it. Until I see it with my own eyes and have to work on a sev 1 at 3AM, I'll reserve judgement.

If you're going for ISO or ITIL certification, I know TOP is designed for that, which is why we implemented it.

Hope this helps.

You can use ONEORZERO TASK management system for IT, I think that is better for u. avaialabe at free download at free cost (GPL).
www.oneorzero.com, Use Apache, Mysql, and PHP engine. If any let me know or mail me at itsmeyaa@gmail.com

I???m using FocalScope for my company and it replaces outlook completely. It is a new help desk system that manages tickets and more than that. It has a clean interface and is relatively easy to use. You could try it out since it???s free for the first 3 licenses. http://www.focalscope.com.
