I need to push the same desktop to multiple student accounts on a w2k platform with winxp clients. How do I do it?

there are a lot web meeting/conference software / service allow you to broadcast your screen to multiple PCs. some of them are fee based, others are free.
As a start, you may want to check this open source software http://italc.sourceforge.net/documentation.php

I'm looking for a how-to doc on  using group policies and/or user profiles on my domain for the students. I'm not familiar with how that would work. I'd like to associate these policies/profiles with the login accounts of either the individual students or student groups. I want to apply these at login. I do not want to save changes made to the profiles when the students log off.  

wouldnt this be just the same as having a roaming profile selected so that the profile is loaded every time a student logs on? This will slow down log on times. Rather at the school that i manage i set it up so that the user profiles were stored on a second parition like d:\ for example then changed the registry to load profiles the d: by default that way when the profiles folders get to large and run out of disk space particularly the older XP machines i just send a .bat file to file d: as schedule task to run every few months.

What is the purpose you are trying to achieve?

To: jaramart: I am not familiar enough with what a roaming profile is or does to answer the question.  I want to take control of the workstations so that the applications needed in the classrooms on a daily basis are available and ready to used daily. I don't want teachers or students changing things on the client machines. I thought I could simply create a client profile on a clean desktop PC, then copy that profile to some area of my windows AD server and reference it in the log on account for the users. When I did that the problem was changes made by the users at the client end were written back to the profile on the server I created and obviously the profile kept changing on me. I thought I could create an environment where changes were not saved back to the server, only sent down to the client refreshed desktop if you will. I do not currently have any group policies or roaming profiles being applied to accounts within the domain for users for that reason. That's why I get Punk'd everyday in this environment and have help desk tickets by the 100's. I'm not very familiar with the way Windows Server and Windows XP Clients would be setup or work together in this regard I guess. I need a group policy/roaming profile for dummies book or lesson.

To raysonlee: Don't apologize. I'm sure I am not explaining this clearly. So you've read my reply to jaramart and I have the expectation of the relationship between the server and the client correct? All I need to do is prevent roaming profile changes from propagating back to the server. Is that correct?

yes, i understand why u want to keep your students and teachers from updating your setup. Standardization is always a must for public environment like yours. Simply follow the configuration for roaming profile and enable prevent roaming profile change propagation setting.

oh ok i get it now. In group Policy you need to configure it so that the students do not have the permissions to change and delete icons desktop themes or printers. What i do is create a sepparte Group Policy for each IE printer and sepparte one for desktops then link it to the group that the students are apart of in AD. and disable all features that enables any client interaction. and push out a selected background. I also change the background once a month to keep the kids amused therefore they dont go looking.
